## Overview

### Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-f5p5-6xmx-p252. This link is maintained to preserve external references.

### Original Description
A flaw was found in Keycloak Policy Enforcer. This vulnerability allows any authenticated user to bypass all authorization policies, including role, scope, and User-Managed Access (UMA) permission checks. By including the configured access-denied page path within a request URL, either as a path segment or a query parameter, an attacker can gain unauthorized access to protected resources.

## Affected packages

- `org.keycloak:keycloak-services < 26.6.4`
- `org.keycloak:keycloak-policy-enforcer < 26.0.10`

## Remediation

Refer to the advisory for the patched release.
