Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: OpenID Connect ID Token signatures were completely unverified by the IdTokenVerifier, allowing attackers to authenticate with forged tokens.
Auth Bypass: Failures during public key retrieval from the certificate endpoint did not throw exceptions, leading applications to bypass signature validation entirely and trust unverified tokens.
Auth Bypass: Failed public key lookups resulted in caching empty key maps, permanently breaking signature verification for subsequent valid tokens in the lifecycle.
