Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Dominant vulnerability class with 46 fixes, many involving missing authorization on referenced resources, weak identity resolution, and overly broad security filter exclusions.

XXE: Multiple XML parsers (SAX, DOM, StAX, TransformerFactory) were found with external entities/DTDs enabled, requiring repeated hardening.

Cryptographic Weakness: Hardcoded default encryption keys and weak key derivation (Bcrypt, DSA 1024, HS256) repeatedly exposed sensitive data.
