Scan Sequence (run in parallel where possible)

SEC-01 — Hardcoded Secrets

# Patterns
grep -rn "API_KEY\s*=\s*['\"][^'\"]\+" src/
grep -rn "SECRET\s*=\s*['\"][^'\"]\+" src/
grep -rn "PASSWORD\s*=\s*['\"][^'\"]\+" src/
grep -rn "TOKEN\s*=\s*['\"][^'\"]\+" src/
grep -rn "(sk-|pk_live_|ghp_|AKIAI)[a-zA-Z0-9]" src/

SEC-02 — localStorage Token Storage

grep -rn "localStorage.setItem.*[Tt]oken\|localStorage.setItem.*[Kk]ey" src/
grep -rn "sessionStorage.setItem.*[Tt]oken" src/

SEC-03 — SQL Injection

grep -rn "query(\`\|query(\"" src/ | grep -v "parameterized\|prepared"
grep -rn "SELECT.*\${.*}\|INSERT.*\${.*}\|WHERE.*\+" src/

SEC-04 — XSS Vectors

grep -rn "dangerouslySetInnerHTML" src/
grep -rn "innerHTML\s*=" src/
grep -rn "document.write(" src/

SEC-05 — eval() / exec()

grep -rn "\beval\b\|new Function(" src/
grep -rn "subprocess.*shell=True" src/
grep -rn "exec(.*req\|exec(.*input\|exec(.*param" src/

SEC-06 — CORS Wildcard

grep -rn "Access-Control-Allow-Origin.*\*" src/
grep -rn "origin.*\*\|cors.*origin.*true" src/

SEC-07 — Auth Bypass Risk

# Routes without auth middleware
grep -rn "router\.\(get\|post\|put\|delete\)" src/api/ | grep -v "auth\|middleware\|protect"

(Requires context analysis — sonnet reviews findings)

SEC-08 — IDOR Risk

# Resource access without ownership check
grep -rn "findById\|getById\|findOne" src/ | grep -v "userId\|ownerId\|where.*user"

(Requires context analysis)

SEC-09 — Unvalidated Input

# API endpoints without input validation
grep -rn "req\.body\|req\.params\|req\.query" src/api/ | grep -v "zod\|validate\|parse\|schema"

SEC-10 — Insecure Randomness

grep -rn "Math.random()\|random.random()" src/ | grep -vi "test\|spec\|mock"

SEC-11 — Path Traversal

grep -rn "fs\.readFile\|fs\.writeFile\|open(" src/ | grep -v "path\.join\|path\.resolve"

SEC-12 — HTTP (non-HTTPS)

grep -rn "http://" src/ | grep -v "localhost\|127.0.0.1\|test\|spec\|comment\|//.*http"

SEC-13 — Sensitive Data in Logs

grep -rn "console\.log.*password\|console\.log.*token\|console\.log.*secret" src/
grep -rn "logger\.info.*password\|log\.Print.*token" src/

SEC-14 — Weak Crypto

grep -rn "md5\|sha1\b\|DES\|RC4\|ECB" src/ | grep -vi "test\|spec\|comment"

SEC-15 — .env in Git

# Check .gitignore
grep -q "\.env" .gitignore || echo "MISSING: .env not in .gitignore"
git ls-files | grep -E "^\.env$|^\.env\."

Severity Levels

| Level | Description | Action | |-------|-------------|--------| | CRITICAL | Active vulnerability, exploit likely | BLOCK — must fix before merge | | HIGH | Serious risk, needs immediate fix | BLOCK | | MEDIUM | Should fix, not immediately dangerous | WARN — track in tech-debt | | LOW | Best practice violation | INFO |

Output Format

All Clear:

## Security Audit
SEC-01~15: Pass
VERDICT: Pass

Issues Found:

## Security Audit

CRITICAL (1):
  SEC-02 [CRITICAL]: localStorage token storage
  File: src/auth/auth.ts:45
  Pattern: localStorage.setItem('token', jwt)
  Fix: httpOnly cookie via server Set-Cookie header

HIGH (1):
  SEC-03 [HIGH]: SQL injection risk
  File: src/api/search.ts:67
  Pattern: db.query(`SELECT * WHERE name = '${query}'`)
  Fix: db.query('SELECT * WHERE name = $1', [query])

MEDIUM (1):
  SEC-10 [MEDIUM]: Insecure randomness for token generation
  File: src/lib/tokens.ts:12
  Pattern: Math.random().toString(36)
  Fix: crypto.randomBytes(32).toString('hex')

VERDICT: FAIL (2 blocking: CRITICAL + HIGH)

Integration

Runs in parallel with validator at Gate 2 (Guardian Team). CRITICAL/HIGH findings → BLOCK Gate 2 regardless of other checks.
