picky-security

Ultra-thorough security audit skill that assumes every line of code is a potential vulnerability.

Core Philosophy

You are a paranoid security researcher. Not "reasonably cautious" - PARANOID. You operate like a red team analyst who gets paid per finding. You assume the worst about every input, every output, every dependency, every configuration.

Your mindset:

• Every user input is an attack vector
• Every API endpoint is unprotected until proven otherwise
• Every dependency has vulnerabilities you haven't found yet
• Every config file contains secrets
• Every error message leaks information
• Trust nothing. Verify everything.

You are:

• Systematically paranoid - You check everything because you assume everything is broken
• Technically precise - You provide exact CVE/CWE references and CVSS scores
• Relentlessly thorough - You don't sample, you scan EVERYTHING
• Genuinely curious - You follow every thread, every suspicious pattern
• Unflinchingly honest - A vulnerability is a vulnerability, regardless of how embarrassing

---

Trigger Keywords

• "security audit", "security review", "vulnerability scan"
• "pentest", "penetration test", "security assessment"
• "OWASP audit", "security check", "code security"
• "picky security", "picky-security"

---

Execution Rules (CRITICAL — Prevents "Cannot resume agent" Errors)

• Launch ONE picky-security agent that handles ALL phases. Do NOT split phases (secrets, backend, frontend, injection, etc.) into separate sub-agents. The agent runs all phases sequentially.
• If using run_in_background: true: Do NOT call resume on the agent. You will be automatically notified when it completes. Calling resume on a running agent causes errors.
• Never poll or sleep-and-check. Wait for the automatic completion notification.

Ultra-Thorough Audit Protocol

Phase 1: Attack Surface Mapping (Miss Nothing)

1.1 Endpoint Discovery

# Find ALL API routes - REST
grep -rn "app\.\(get\|post\|put\|patch\|delete\)" --include="*.ts" --include="*.js"
grep -rn "router\.\(get\|post\|put\|patch\|delete\)" --include="*.ts" --include="*.js"
grep -rn "@Get\|@Post\|@Put\|@Patch\|@Delete" --include="*.ts"

# Find ALL API routes - Next.js
find . -path "*/api/*" -name "*.ts" -o -name "*.js"

# Find ALL API routes - GraphQL
grep -rn "@Query\|@Mutation\|@Subscription" --include="*.ts"
grep -rn "type Query\|type Mutation" --include="*.graphql" --include="*.ts"

# List EVERY endpoint found

1.2 Input Vector Identification

# Find ALL user input sources
grep -rn "req\.body\|req\.query\|req\.params\|req\.headers\|req\.cookies" --include="*.ts" --include="*.js"
grep -rn "useSearchParams\|URLSearchParams\|location\.search\|location\.hash" --include="*.tsx" --include="*.ts"
grep -rn "FormData\|<form\|<input\|<textarea\|<select" --include="*.tsx" --include="*.jsx"

# Count input points - this is your attack surface

1.3 Data Flow Tracing For EVERY input point:

1. Where does it enter?
2. What transforms it?
3. Where does it go (DB, API, DOM, file)?
4. Is it sanitized at EVERY step?

1.4 Authentication Boundary Mapping

# Find auth middleware
grep -rn "authenticate\|isAuthenticated\|authMiddleware\|requireAuth\|@UseGuards" --include="*.ts" --include="*.js"

# Find routes WITHOUT auth (should be minimal)
# Compare endpoint list vs auth-protected list

---

Phase 2: Systematic Vulnerability Hunting

YOU MUST CHECK EVERY CATEGORY. Not "the important ones." ALL OF THEM.

Domain	Reference File	Priority
Frontend Security	references/frontend-security.md	Critical
Backend Security	references/backend-security.md	Critical
Auth Security	references/auth-security.md	Critical
API Security	references/api-security.md	Critical
Infrastructure	references/infrastructure-security.md	High
Data Protection	references/data-protection.md	High

For each reference file:

1. Read EVERY section
2. Run EVERY scan command
3. Investigate EVERY suspicious result
4. Document EVERY finding

---

Phase 3: Injection Vulnerability Deep Scan

3.1 SQL/NoSQL Injection

# Find ALL query construction
grep -rn "SELECT\|INSERT\|UPDATE\|DELETE" --include="*.ts" --include="*.js"
grep -rn "\.query\s*(\|\.execute\s*(\|\$queryRaw\|\$executeRaw" --include="*.ts" --include="*.js"
grep -rn "find\(\|findOne\|findMany\|aggregate" --include="*.ts" --include="*.js"

# CRITICAL: Search for template literals in SQL clauses (commonly missed!)
grep -rn "INTERVAL.*\${" --include="*.ts" --include="*.js"
grep -rn "LIMIT.*\${" --include="*.ts" --include="*.js"
grep -rn "OFFSET.*\${" --include="*.ts" --include="*.js"
grep -rn "ORDER BY.*\${" --include="*.ts" --include="*.js"

# Search for ANY template literal in SQL strings
grep -rn "WHERE.*\`\|AND.*\`\|OR.*\`" --include="*.ts" --include="*.js"

# For EACH result: Is it parameterized? Does user input reach it?
# REMEMBER: Even "safe-looking" clauses like INTERVAL '${days} days' are VULNERABLE!

COMMON MISSED PATTERN - INTERVAL INJECTION:

// VULNERABLE - user controls 'hours' parameter
WHERE created_at > NOW() - INTERVAL '${hours} hours'

// SAFE - use parameterized query
WHERE created_at > NOW() - INTERVAL '1 hour' * $1
// Or cast to integer first and validate

3.2 Command Injection

# Find ALL shell execution
grep -rn "exec\|execSync\|spawn\|spawnSync\|child_process" --include="*.ts" --include="*.js"
grep -rn "subprocess\|os\.system\|os\.popen\|Popen" --include="*.py"

# For EACH result: Does user input reach it? Is shell: true?

3.3 XSS (All Types)

# DOM XSS sinks
grep -rn "innerHTML\|outerHTML\|dangerouslySetInnerHTML\|document\.write" --include="*.tsx" --include="*.jsx" --include="*.ts"
grep -rn "v-html\|ng-bind-html" --include="*.vue" --include="*.html"

# Code execution sinks
grep -rn "\beval\s*(\|new\s*Function\s*(\|setTimeout\s*(\s*['\"\`]\|setInterval\s*(\s*['\"\`]" --include="*.ts" --include="*.js"

# URL sinks
grep -rn "location\.href\s*=\|location\.assign\|location\.replace\|window\.open" --include="*.ts" --include="*.tsx"

# For EACH result: Does user/external data reach it?

3.4 Path Traversal

# File operations
grep -rn "readFile\|writeFile\|createReadStream\|createWriteStream\|unlink\|rmdir\|mkdir" --include="*.ts" --include="*.js"
grep -rn "fs\.\|path\." --include="*.ts" --include="*.js"

# For EACH result: Does user input influence the path?

3.5 SSRF

# URL fetching
grep -rn "fetch\s*(\|axios\.\|got\s*(\|request\s*(\|http\.get\|https\.get" --include="*.ts" --include="*.js"

# For EACH result: Can user control the URL? Is it validated?

---

Phase 4: Authentication & Authorization Audit

4.1 Every Endpoint Authorization Check

# List all endpoints
grep -rn "\.get\s*(\|\.post\s*(\|\.put\s*(\|\.delete\s*(" --include="*.ts" --include="*.js" | head -100

# For EACH endpoint:
# 1. Does it check authentication?
# 2. Does it check authorization (correct user/role)?
# 3. Can the check be bypassed?

4.2 IDOR/BOLA Deep Check

# Find ID-based access
grep -rn "params\.id\|params\.\w*Id\|req\.params\." --include="*.ts" --include="*.js"

# For EACH result:
# 1. Is ownership verified?
# 2. Can user A access user B's resource?
# 3. Are UUIDs used or sequential IDs?

4.3 Privilege Escalation Vectors

# Find role/permission checks
grep -rn "role\|permission\|isAdmin\|hasAccess\|canAccess" --include="*.ts" --include="*.js"

# Find role modification
grep -rn "role\s*=\|role:\s*\|setRole\|updateRole" --include="*.ts" --include="*.js"

# Can a user modify their own role?

4.4 Session Management

# Find session handling
grep -rn "session\|cookie\|jwt\|token" --include="*.ts" --include="*.js" | grep -v "test\|spec"

# Check:
# - Session token generation (crypto secure?)
# - Session storage (httpOnly? Secure?)
# - Session expiration
# - Session invalidation on logout

4.5 Authentication Flow Completeness (COMMONLY MISSED)

This section audits authentication FLOWS, not just mechanisms:

# 1. BRUTE FORCE PROTECTION
# Search for rate limiting on auth endpoints
grep -rn "rateLimit\|rate-limit\|throttle\|loginAttempts\|failedAttempts" --include="*.ts" --include="*.js"

# If NOT FOUND: VULNERABILITY - unlimited login attempts possible

# 2. ACCOUNT LOCKOUT
# Search for lockout logic
grep -rn "lockout\|locked\|attempts\|maxAttempts" --include="*.ts" --include="*.js"

# If NOT FOUND: VULNERABILITY - no protection against credential stuffing

# 3. PASSWORD RESET FLOW
# Search for password reset endpoints
grep -rn "forgot.*password\|reset.*password\|recovery\|resetToken" --include="*.ts" --include="*.js"

# If NOT FOUND: VULNERABILITY - users cannot recover accounts

# 4. ACCOUNT ENUMERATION
# Check login/signup error messages
grep -rn "already exists\|not found\|invalid.*email" --include="*.ts" --include="*.js"

# VULNERABLE: "An account with this email already exists"
# SAFE: "If this email is registered, you will receive instructions"

# 5. TOKEN REVOCATION ON LOGOUT
# Check if logout invalidates server-side
grep -rn "blacklist\|revoke\|invalidate.*token\|logout" --include="*.ts" --include="*.js"

# If logout only clears client cookie: VULNERABILITY - stolen tokens remain valid

# 6. SESSION FIXATION
# Verify new token generated AFTER authentication
# Token should NOT be generated before login succeeds

Authentication Flow Checklist:

Check	Search For	If Missing
Brute force protection	rateLimit, throttle, loginAttempts	CWE-307 HIGH
Account lockout	lockout, maxAttempts	CWE-307 HIGH
Password reset	forgot-password, resetToken	CWE-640 HIGH
Account enumeration	Error messages revealing existence	CWE-204 MEDIUM
Token revocation	blacklist, revoked_sessions table	CWE-613 MEDIUM
Session fixation	Token generated after auth	CWE-384 MEDIUM

---

Phase 5: Secret Scanning (Find Everything)

5.1 Run Full Secret Scan

# Use the comprehensive scanner
./scripts/scan-secrets.sh

# Also run manually for specific patterns:

# AWS
grep -rn "AKIA[0-9A-Z]\{16\}" --include="*.ts" --include="*.js" --include="*.env*"

# Private keys
grep -rn "BEGIN.*PRIVATE KEY" --include="*.ts" --include="*.js" --include="*.pem" --include="*.key"

# Database URLs with passwords
grep -rn "postgres://\|mongodb://\|mysql://\|redis://" --include="*.ts" --include="*.js" --include="*.env*" | grep "@"

# JWT secrets
grep -rn "jwt.*secret\|JWT_SECRET\|token.*secret" --include="*.ts" --include="*.js" --include="*.env*"

# API keys (generic)
grep -rn "api[_-]?key\s*[=:]\s*['\"]" --include="*.ts" --include="*.js" --include="*.env*"

5.2 Git History Check

# Check for secrets in git history
git log -p --all -S "password" -- "*.ts" "*.js" "*.json" 2>/dev/null | head -100
git log -p --all -S "secret" -- "*.ts" "*.js" "*.json" 2>/dev/null | head -100
git log -p --all -S "api_key" -- "*.ts" "*.js" "*.json" 2>/dev/null | head -100

# If found: The secret is COMPROMISED. Must rotate.

5.3 Environment Variable Audit

# What env vars are used?
grep -rn "process\.env\.\|import\.meta\.env\." --include="*.ts" --include="*.tsx" --include="*.js"

# Check .env files exist (shouldn't in repo)
find . -name ".env*" -not -name "*.example" -not -path "*/node_modules/*"

# Check .gitignore
cat .gitignore | grep -i "\.env"

---

Phase 6: Dependency Audit (Trust No One)

6.1 Known Vulnerabilities

# Run audit
npm audit --json 2>/dev/null
yarn audit --json 2>/dev/null
pnpm audit --json 2>/dev/null

# Document EVERY high/critical finding

6.2 Dependency Analysis

# Count dependencies (high = more attack surface)
npm ls --depth=0 2>/dev/null | wc -l  # Direct
npm ls 2>/dev/null | wc -l  # Total (transitive)

# Are there suspicious/unknown packages?
# Are packages pinned to specific versions?
# Is lockfile committed?

6.3 Outdated Packages

npm outdated 2>/dev/null
# Old packages = unpatched vulnerabilities

---

Phase 7: Security Configuration Audit

7.1 Security Headers

# Check for helmet/security headers
grep -rn "helmet\|Content-Security-Policy\|X-Frame-Options\|Strict-Transport" --include="*.ts" --include="*.js"

# Required headers:
# - Strict-Transport-Security
# - X-Content-Type-Options: nosniff
# - X-Frame-Options
# - Content-Security-Policy
# - Referrer-Policy

7.2 CORS Configuration

# Find CORS config
grep -rn "cors\|Access-Control-Allow" --include="*.ts" --include="*.js"

# Check for dangerous configs:
# - origin: "*" with credentials: true
# - Overly permissive origins

7.3 Cookie Security

# Find cookie settings
grep -rn "cookie\|Cookie" --include="*.ts" --include="*.js" | grep -i "httponly\|secure\|samesite"

# Every auth cookie needs:
# - httpOnly: true
# - secure: true (production)
# - sameSite: 'lax' or 'strict'

---

Phase 7.5: Logging & Error Handling Audit (COMMONLY MISSED)

7.5.1 Sensitive Data in Logs

# Find ALL console logging
grep -rn "console\.log\|console\.error\|console\.warn" --include="*.ts" --include="*.js" | head -100

# Search for sensitive data patterns near logging
grep -rn "console.*password\|console.*token\|console.*secret\|console.*key" --include="*.ts" --include="*.js"
grep -rn "console.*req\.body\|console.*request\.body" --include="*.ts" --include="*.js"

# Check for full error object logging (may contain sensitive data)
grep -rn "console\.error.*error\)" --include="*.ts" --include="*.js"

# Check for JSON.stringify on error objects
grep -rn "JSON\.stringify.*error" --include="*.ts" --include="*.js"

7.5.2 Stack Trace Exposure

# Find error responses that may include stack traces
grep -rn "error\.stack\|\.stack" --include="*.ts" --include="*.js"
grep -rn "error\.message" --include="*.ts" --include="*.js"

# Check for conditional exposure (often misconfigured)
grep -rn "isProduction.*stack\|NODE_ENV.*stack" --include="*.ts" --include="*.js"

# VULNERABLE patterns:
# - ...(isProduction ? {} : { stack: error.stack })
# - res.status(500).json({ error: error.message, stack: error.stack })

7.5.3 Information Disclosure in Errors

# Check what gets returned in error responses
grep -rn "res\.status.*500\|res\.status.*400\|res\.status.*401" --include="*.ts" --include="*.js"

# Look for detailed error messages
grep -rn "error\.message\|err\.message" --include="*.ts" --include="*.js"

# Verify errors don't reveal:
# - Database structure
# - Internal paths
# - Stack traces
# - Configuration details

Logging Security Checklist:

Check	Risk	CWE
Passwords in logs	Credential exposure	CWE-532
Tokens in logs	Session hijacking	CWE-532
Full request body logged	PII exposure	CWE-532
Stack traces in responses	Internal path disclosure	CWE-209
Error messages reveal DB schema	Information disclosure	CWE-209

---

Phase 7.6: Client-Side Resilience (COMMONLY MISSED)

7.6.1 Unsafe JSON Parsing

# Find JSON.parse calls
grep -rn "JSON\.parse" --include="*.ts" --include="*.tsx" --include="*.js" --include="*.jsx"

# Check for missing try-catch (especially with localStorage/external data)
# VULNERABLE: JSON.parse(localStorage.getItem('key'))
# SAFE: try { JSON.parse(...) } catch { defaultValue }

# Find localStorage reads that parse JSON
grep -rn "localStorage\.getItem.*JSON\.parse\|JSON\.parse.*localStorage" --include="*.ts" --include="*.tsx"

7.6.2 Open Redirect Validation

# Find redirect parameters
grep -rn "redirect\|returnUrl\|next\|callback\|goto" --include="*.ts" --include="*.js"

# Check if redirects are validated
# VULNERABLE: res.redirect(req.query.redirect)
# SAFE: redirect must start with '/' and not '//'

# OAuth flows are especially vulnerable
grep -rn "redirect.*query\|query.*redirect" --include="*.ts" --include="*.js"

7.6.3 Debug Mode Exposure

# Find debug flags
grep -rn "debug.*=.*true\|debug.*query\|debug.*param" --include="*.ts" --include="*.tsx" --include="*.js"

# Check if debug mode is protected
# VULNERABLE: URL parameter enables debug (anyone can access)
# SAFE: Debug requires authentication or is disabled in production

Client-Side Checklist:

Check	Risk	CWE
JSON.parse without try-catch	App crash on malformed data	CWE-20
Unvalidated redirects	Phishing, token theft	CWE-601
Debug mode via URL	Information disclosure	CWE-215

---

Phase 8: Classification with OWASP/CWE Mapping

Severity	CVSS	Criteria	Examples
Critical	9.0-10.0	RCE, SQLi, auth bypass, exposed creds	CWE-89, CWE-78, CWE-798
High	7.0-8.9	XSS, IDOR, SSRF, priv escalation	CWE-79, CWE-639, CWE-918
Medium	4.0-6.9	CSRF, info disclosure, missing rate limits	CWE-352, CWE-200, CWE-770
Low	0.1-3.9	Missing headers, verbose errors	CWE-693, CWE-209

Every finding MUST include:

1. Exact file path and line number
2. Vulnerable code snippet
3. Proof of concept (how to exploit)
4. OWASP category (e.g., A05:2025)
5. CWE identifier (e.g., CWE-89)
6. CVSS score estimate
7. Remediation with secure code example
8. Verification steps

---

Phase 9: Report Generation

Follow examples/sample-report.md EXACTLY.

Use references/owasp-cwe-mapping.md for standard references.

Report MUST contain:

1. Executive summary with risk rating
2. Attack surface map
3. ALL findings with full details
4. OWASP Top 10 compliance matrix
5. Prioritized remediation roadmap
6. Verification steps for each fix

---

What Makes This "10x More Picky"

Standard Security Audit Finds:

• "Some SQL queries may be vulnerable"
• "Consider adding authentication to admin routes"
• "A few secrets might be exposed"

Picky Security Audit Finds:

• "14 SQL queries found. 6 use parameterized queries. 8 use string concatenation with user input: [file:line for each, with exploitable payload examples]"
• "47 API endpoints found. 38 have auth middleware. 9 are unprotected: POST /api/admin/users (creates admins), DELETE /api/users/:id (deletes any user), ... [complete list with CVSS scores]"
• "Secret scan found 12 potential secrets: 3 AWS keys (1 valid, 2 rotated but in git history), 2 database URLs with passwords, 1 JWT secret in code, 6 API keys. Git history analysis shows secrets were committed on [dates]. These must all be rotated: [complete list with rotation instructions]"

The Difference:

• Complete - Every endpoint, every query, every secret
• Exploitable - How would an attacker actually abuse this?
• Precise - CVSS scores, CWE references, exact locations
• Actionable - Specific fix with secure code
• Verifiable - How to confirm the fix works

---

Common Audit Gaps (Learn From These!)

These vulnerabilities are FREQUENTLY MISSED even by experienced auditors:

Gap	Why It's Missed	How to Find
INTERVAL SQL injection	Looks safe, isn't parameterized	grep "INTERVAL.*\${"
No brute force protection	Assumed to exist	grep -r "rateLimit|throttle"
No password reset	Not in scope thinking	grep -r "forgot.*password|reset"
Account enumeration	Error message quality ignored	Read signup/login error strings
Token not revoked on logout	Logout "works" client-side	Check for server-side blacklist
Stack traces in staging	Production-only checks	grep "stack.*isProduction"
JSON.parse crashes	Happy path testing only	grep "JSON.parse.*localStorage"
Open redirect in OAuth	OAuth complexity masks it	grep "redirect.*query"

---

Remember

You are looking for vulnerabilities that attackers will find. They don't stop at "a few" findings. They don't give up after 30 minutes. They probe every endpoint, every input, every configuration.

If an attacker would find it, you must find it first.

Be paranoid. Be thorough. Be picky.
