Kerentanan Incorrect Behavior Order: Authorization Before Parsing and Canonicalization pada redhat build of keycloak, redhat data grid +2 lainnya. Skor CVSS 3.1 8.1 (High) menurut redhat.com.

Deskripsi (NVD)

A 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.
