Recurring patterns

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

Deserialization of Untrusted Data: Unsafe deserialization allowed arbitrary class loading and code execution when processing JSON metadata. This is a critical risk addressed via strict classname allowlisting.

Command Injection: Executing commands inside an intermediate system shell wrapper allowed shell command injection, requiring direct raw array execution without shell parsing.

Auth Bypass: Implicit session creation when retrieving or invalidating sessions could bypass intended authentication flow logic.
