A GitHub-reviewed security advisory, not necessarily under active exploitation the way our CISA KEV advisories are, but a real, disclosed vulnerability in an open-source dependency.
Affected packages
Vulnerable: < 26.6.4
Patched in 26.6.4
Vulnerable: < 26.0.10
Patched in 26.0.10
Details
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.
EPSS, exploit probability
Low0.65%
estimated chance of real-world exploitation in the next 30 days, higher than 51.1% of every CVE FIRST.org scores
Refreshed 10/29/2026, via FIRST.org's EPSS model, not CVSS, this measures likelihood of exploitation, not how severe it would be.
