Attack Vector & Structural Vulnerability Analysis
Wildcard Access-Control-Allow-Origin headers configured with Access-Control-Allow-Credentials allow untrusted external origins to make authenticated API requests.
Non-Intrusive Diagnostic Verification Protocol
Tests preflight OPTIONS requests across custom origin headers to verify explicit domain allowlisting and reject unvalidated origin reflection.
Taxonomy Classification
