Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Incomplete server verification in the SCRAM client implementation allows a malicious or compromised server to completely bypass mutual authentication checks, misleading the client into believing a secure handshake occurred.
Auth Bypass: Logic flaws during the multi-stage authentication sequence can lead to premature exits, such as skipping mandatory proxy mutual authentication because of short-circuiting logic in the target verification steps.
Auth Bypass: Authorization header leakage can occur when Basic authentication credentials are not correctly confined to their exact path prefix during state resets on subsequent requests to the same host.
