Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Gating flaws on proxy and image generation endpoints allowed clients to bypass intended model limits, API-key quotas, and reasoning constraints when accessing upstream services.
Denial of Service: Unbounded streaming, long-lived database transactions, and missing cleanup blocks on request retries regularly caused database connection pool exhaustion and semaphore starvation.
Denial of Service: Unbounded decompression streams allowed clients to send compressed payloads (such as zstd decompression bombs) that consume excessive memory and crash the proxy service.
