Escape with javax.naming.ldap.Rdn.escapeValue or equivalent. For python-ldap, use ldap.filter.escape_filter_chars. Better: use parameterized search APIs (Spring LdapTemplate filter encoders).

medium Security checks quality Quality conf 1.00 [SEC123] Production stack trace / debug output exposed: Debug mode left on in production exposes stack traces, environment variables, framework internals — sometimes triggers RCE (Django debug page with arbitrary template eval).

Set DEBUG=False / APP_DEBUG=false in production. Provide a generic 500 handler that logs to backend but returns a sanitized page to clients.

low Security checks quality Error handling conf 0.55 ✓ Repobility 2 occurrences Broad exception handler needs review

This handler catches Exception/BaseException. It is actionable when it swallows errors without logging, re-raising, or returning a structured error. Handlers that intentionally convert exceptions into typed error results should not be treated as high risk.

CI tokens with write permissions increase blast radius when an action, dependency, or PR workflow is compromised. Prefer job-level least-privilege permissions.

`requests.get(...)` here lacks both a `timeout=` arg and an enclosing try/except. This is exactly the class of bug that took down our git-clone earlier (HTTP/2 stream cancel surfaced as a fatal). Add a `timeout=` and wrap in try/except, or use a wrapper that retries.

The scanner did not find any standard auth library (JWT, OAuth, NextAuth, Auth0, etc.). Either auth lives in custom code, in a separate service, or is missing.

Duplicate implementation blocks are maintenance debt. Keep them visible, but they are not a high-severity defect unless the duplicated logic is security-sensitive or drifting.
