They come from `security/17-security-pattern.md` and are non-negotiable. No deadline, no convenience argument overrides them. + +### RULE 1 โ€” Secrets are never in code +Secrets (JWT_SECRET, API keys, DB passwords, private keys) live in environment variables or a secrets vault. Never in source code. The application **must fail at startup** if a required secret is missing โ€” no fallbacks, no defaults. + +```javascript +// CORRECT โ€” fail-fast secret loading +const JWT_SECRET = process.env.JWT_SECRET; +if (!JWT_SECRET) { + console.error("FATAL: JWT_SECRET is not set. Refusing to start."); + process.exit(1); +} +``` + +### RULE 2 โ€” Tokens live in HttpOnly cookies +Access tokens and refresh tokens are stored in `HttpOnly; Secure; SameSite=Lax` cookies. Never in `localStorage`, `sessionStorage`, or JavaScript-accessible cookies. Tokens are never returned in response bodies in production. + +### RULE 3 โ€” JWT algorithm is fixed and verified +The algorithm is hardcoded in the verification call. `alg: none` is explicitly rejected. The token's own `alg` claim is never trusted. + +```javascript +// CORRECT +jwt.verify(token, JWT_SECRET, { algorithms: ['HS256'] }); + +// CORRECT (RS256 with JWKS) +const client = jwksClient({ jwksUri: `${IDP_URL}/.well-known/jwks.json` }); +// algorithm explicitly set to RS256 โ€” never 'none', never from token header +``` + +### RULE 4 โ€” Roles come from the IdP, always +The Identity Provider is the single source of truth for roles and permissions. Local database roles are a cache โ€” they are re-synced from the IdP on every login. A local role that contradicts the IdP is always overwritten by the IdP. + +### RULE 5 โ€” Sensitive data is never logged +Tokens, passwords, secrets, API keys, cookie values, PII (CPF, email in full, credit card data) are never written to any log stream โ€” not debug, not info, not error. Mask or omit them. + +```javascript +// CORRECT โ€” log user context without sensitive data +logger.info({ userId: user.id, action: 'login', ip: req.ip }); + +// WRONG +logger.info({ user, token, password }); +``` + +### RULE 6 โ€” CORS is an allowlist, not a wildcard +In production, `Access-Control-Allow-Origin` is an explicit list of known origins. `*` is never used on endpoints that accept cookies or Authorization headers. `Access-Control-Allow-Credentials: true` requires an explicit origin โ€” it never works with `*`. + +### RULE 7 โ€” Every auth route has rate limiting +Login, registration, password reset, MFA verification, and token refresh endpoints have rate limiting by IP (and by user where applicable). HTTP 429 is returned when the limit is exceeded. + +### RULE 8 โ€” All inputs are validated at the trust boundary +Every external input โ€” request body, query params, headers, path params โ€” is validated against a strict schema before reaching business logic. ORM or parameterized queries are used for all database interactions. String concatenation into SQL is never acceptable. + +--- + +## ๐Ÿ”Ž SAST & Secrets Detection โ€” Full Pattern Reference + +### Authentication & JWT + +| Pattern | Severity | Standard | +|---------|----------|----------| +| `jwt.decode(token)` without verify | CRITICAL | ยง3.1 | +| `algorithms: ['none']` or `algorithm: 'none'` | CRITICAL | ยง3.1, ยง5.1 | +| `jwt.verify(token, secret)` without algorithm option | CRITICAL | ยง5.1 | +| JWT secret in code literal | CRITICAL | ยง5.1, ยง11.1 | +| `JWT_SECRET || "fallback"` | CRITICAL | ยง5.1 | +| No `iss`, `aud`, `exp` validation | HIGH | ยง5.1 | + +### Secrets & Environment + +| Pattern | Severity | Standard | +|---------|----------|----------| +| Hardcoded password/key/secret literal | CRITICAL | ยง11.1 | +| Insecure `os.getenv("X", "default")` for secrets | CRITICAL | ยง11.1 | +| Private key PEM material in source | CRITICAL | ยง11.1 | +| AWS/GCP/Azure credential patterns | CRITICAL | ยง11.1 | +| `.env` file committed (not in `.gitignore`) | HIGH | ยง11.1 | +| Secret shared across environments | HIGH | ยง11.1 | + +### Logging + +| Pattern | Severity | Standard | +|---------|----------|----------| +| `log(token)`, `log(password)`, `log(secret)` | HIGH | ยง12.2 | +| Error response with `err.stack` | HIGH | ยง13 | +| PII (email, CPF, card) in log statements | HIGH | ยง12.2 | +| Request body logged entirely | MEDIUM | ยง12.2 | + +### Storage & Cookies + +| Pattern | Severity | Standard | +|---------|----------|----------| +| `localStorage.setItem('token', ...)` | HIGH | ยง6.1, ยง14 | +| `sessionStorage.setItem('token', ...)` | HIGH | ยง6.1, ยง14 | +| Cookie without `HttpOnly` flag | HIGH | ยง6.1 | +| Cookie without `Secure` flag (production) | HIGH | ยง6.1 | +| Cookie without `SameSite` | MEDIUM | ยง6.1 | + +### CORS & Headers + +| Pattern | Severity | Standard | +|---------|----------|----------| +| `Access-Control-Allow-Origin: *` on auth API | HIGH | ยง8.1 | +| `cors()` with no origin restriction | HIGH | ยง8.1 | +| Missing `Strict-Transport-Security` header | MEDIUM | ยง7 | +| Missing `X-Content-Type-Options: nosniff` | MEDIUM | ยง7 | +| Missing `X-Frame-Options` | MEDIUM | ยง7 | +| Missing `Content-Security-Policy` | MEDIUM | ยง10 | + +### Database & Injection + +| Pattern | Severity | Standard | +|---------|----------|----------| +| String interpolation in SQL query | CRITICAL | ยง15 | +| `.raw()` with user-supplied input | CRITICAL | ยง15 | +| `eval()` with external data | CRITICAL | ยง14 | +| `innerHTML =` with user data | HIGH | ยง14 | +| `dangerouslySetInnerHTML` without sanitization | HIGH | ยง14 | + +### API Security + +| Pattern | Severity | Standard | +|---------|----------|----------| +| Sequential integer IDs in public endpoints | MEDIUM | ยง13 | +| No input schema validation | HIGH | ยง13 | +| No pagination on list endpoints | LOW | ยง13 | +| Unversioned API routes | LOW | ยง13 | + +--- + +## ๐Ÿ“‹ Security Implementation Reference + +### Fail-Fast Secret Bootstrap + +```typescript +// TypeScript / Node.js โ€” fail at startup if secrets missing +function requireEnv(name: string): string { + const value = process.env[name];
