Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: The authentication proxy layer previously suffered from a vulnerability where multiple or ambiguous credentials could be silently merged or shadowed. This allowed credential leakage to upstream backends and potential auth bypasses if single-credential rules were not strictly enforced during inbound resolution.
Denial of Service: Rigid request serialization locks without client disconnect detection can lead to GPU and compute exhaustion when handling abandoned requests. Implementing robust connection-aware queue mechanisms is critical to preventing resource-starvation DoS.
Denial of Service: Executing blocking operations synchronously (such as using subprocess.run during model unloads) blocks the main server event loop, causing severe service degradation and application-wide hangs.
