Recurring patterns

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

Auth Bypass: Multiple fixes address session lifecycle gaps (revocation, cache invalidation) and token/actor misbinding, allowing revoked or stale credentials to continue accessing data.

Access Control: Filesystem write operations have repeatedly lacked ownership/ACL checks, allowing share recipients or unprivileged actors to write to unauthorized paths.

Privilege Escalation: Permission parsing and mode cascade bugs allowed scoped grants to elevate to broader filesystem access; incorrect actor vs user use and higher-mode implicators were exploited.
