Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Accepting signatures with created timestamps in the future bypasses time-window checks, allowing out-of-window signatures to pass verification.
Authentication Bypass: Expired signatures were accepted because expiry was not enforced before crypto verification, enabling replay of stale credentials.
Signature Replay: Signatures with empty component lists were not bound to any authority or target URI, allowing replay against any endpoint.
