CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:NA flaw was found in Keycloak's Authorization Services. The component responsible for matching request paths to security policies (PathMatcher) does not properly normalize URIs before comparison. By adding extra characters like a trailing slash or matrix parameters to a URL, an attacker can trick the system into applying a less restrictive security policy than intended. This allows an authenticated user to access administrative or restricted areas they should not have permission to see.
Multiple vulnerabilities have been discovered in Keycloak, potentially allowing for privilege escalation, denial of service attacks, and data compromise. These vulnerabilities affect versions 26.6.x through 26.6.5, 26.7.…
