Recurring patterns

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

Use After Free: Vulnerabilities in the Lua garbage collection and state management process can lead to critical memory corruption and potential Remote Code Execution when script objects are freed prematurely. This was highlighted in multiple regressions and the prominent CVE-2024-46981 / CVE-2025-49844.

Denial of Service: Unauthenticated clients can cause server crashes or memory exhaustion by sending highly fragmented, oversized, or nested multibulk commands that bypass standard query buffer limit policies.

Auth Bypass: Logic flaws in the ACL engine (such as command renaming lookups, malformed nested parentheses evaluation, and incorrect flag state clearance) can silently allow execution of restricted write commands or access to protected databases.
