Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Incomplete execution flow control and missing signature key existence validations in OAuth2 token verification allowed critical authentication checks to be bypassed entirely.

SSRF: Improper validation of target metadata endpoints using host instead of hostname, combined with weak validation of AWS IMDS targets, exposed the authentication clients to SSRF and AWS credential extraction.

Cryptographic Signature Bypass: Selecting a generic hash algorithm string rather than the explicit asymmetric key-specific signature scheme resulted in weakened cryptographic verification operations.
