Recurring patterns

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

Auth Bypass: Regular user sessions could collide with the reserved internal/privileged session ID 1 due to insufficient candidate ID boundaries during session initialization.
Out-of-bounds Read: MySQL handshake packet decoding utilized unsafe strlen calls on untrusted input buffers, creating risks of information disclosure or process crashes.
Use After Free: Unvalidated or uninitialized tenant ID evaluations bypassed safety checks, causing memory nodes to be prematurely retired and freed while active references persisted.
