Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Misalignments or incorrect registration of PathPatternRequestMatcher and its Builder bean can cause security configurations to skip custom path rules, leading to direct authorization bypasses on protected endpoints.
Auth Bypass: Parsing X.509 certificate subject DNs using incorrect principal extraction patterns or ignoring RDN ordering allows attackers to spoof identities by structuring malicious certificate attributes.
Open Redirect: Incomplete validation of redirect URIs in authorization server registration and error handling paths enables attackers to craft open redirect attacks targeting end users.
