info Security checks software Ssrf conf 1.00 [SEC029] Server-Side Request Forgery (SSRF) — outbound HTTP from user input: Outbound HTTP request to a user-controlled URL without allowlist validation. Attackers can probe internal services (169.254.169.254 metadata, internal Kubernetes endpoints, file:// URIs), exfiltrate data, or pivot through your network. SSRF is OWASP A10:2021 and a frequent foothold in cloud breaches.

Validate the URL against an allowlist BEFORE fetching: ALLOWED = {'images.example.com', 'cdn.example.com'} host = urlparse(url).hostname if host not in ALLOWED: abort(400) Or use a server-side proxy (Imgproxy / serve-files-only-from-S3) that isolates outbound network access from the request h…

info Security checks quality Quality conf 1.00 3 occurrences [SEC135] Auth/permission check missing on AI-generated endpoint: Mutating HTTP endpoint generated by an AI agent without an auth decorator or middleware. The number-one production-incident pattern we see in AI-generated SaaS code: the AI builds the route, builds the handler, and forgets to wire the auth check that the rest of the codebase uses. CWE-862 (missing authorization). High-severity because the route is fully functional, just unprotected — attackers can call it directly.

Add the project's auth decorator/middleware: `@login_required` (Django/Flask), `@permission_classes([IsAuthenticated])` (DRF), `Depends(get_current_user)` (FastAPI), `requireAuth` middleware (Express). For genuinely public endpoints, add a `# public-endpoint` marker comment so future scans skip the…

info Security checks security Injection conf 1.00 [SEC045] eval()/exec() on stored or user-supplied data: eval() and exec() on data — even admin-stored data — is a lateral-movement vector after any one credential compromise. Sandboxes (__builtins__ cleared) are escapable: attackers use object introspection (().__class__.__mro__[-1].__subclasses__()) to reach os.system. CWE-95 (eval injection).

For literal data structures: use ast.literal_eval(text) — only parses literals, raises on code. For formula evaluation: use asteval or simpleeval (purpose-built sandboxes with allow-lists). For Odoo: use odoo.tools.safe_eval(expr, locals_dict, mode='exec'). If you genuinely need to execute admin-st…

info Security checks quality Quality conf 1.00 [SEC134] AI scaffold leftover — Lorem ipsum / example.com / John Doe in code: Lorem ipsum / John Doe / example.com left in non-test code. AI agents emit these as 'reasonable defaults' when they don't know real values; the human then forgets to swap them. In production, these break demo flows, send mail to a real example.com host (it's owned by IANA), and leak that the codebase had an AI scaffolding pass.

Move dummy values to fixtures / seed files. In application code, require these to come from config or fail closed. Add a CI grep that rejects 'lorem ipsum' and 'example.com' outside test files.

info Security checks quality Quality conf 0.45 [SEC132] String concat where the language has interpolation (AI style drift): String built by concatenation where the language has cleaner interpolation (Python f-strings since 3.6, JS template literals since ES6). Not a vulnerability on its own, but a style signature of cross-language AI rewrites — the model wrote idiomatic Java/C# and then translated mechanically. When this style appears in only *some* files of a repo, it's a strong indicator of an AI-driven rewrite that needs a human review p

This hit is in a test, sample, or example path. It is useful as polish/teaching-surface feedback, but should not dominate production risk scoring.
