Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Inactive API keys could be incorrectly matched and validated, allowing unauthorized clients to bypass authentication checks and access restricted endpoints. Ensure all query lookups explicitly assert active status.
Information Disclosure: Sensitive verification tokens were included during standard model serialization, exposing credentials in outbound responses or logs. Serialization logic must strictly exclude secrets.
Denial of Service: The lack of file size limits on upload endpoints allowed potential resource exhaustion attacks. All file ingestion paths must enforce strict payload constraints early in the request lifecycle.
