CVE-2026-9795 (GCVE-0-2026-9795)

Vulnerability from cvelistv5 – Published: 2026-05-28 03:49 – Updated: 2026-07-15 00:38

Title

Keycloak: keycloak: privilege escalation via improper scope mapping enforcement

Summary

A flaw was found in Keycloak's Fine-Grained Admin Permissions (FGAPv2) feature. An administrator with limited client management permissions can exploit this vulnerability to assign any realm role, including highly privileged roles, to a client's scope mapping. This bypasses intended security controls, allowing the injected role to be projected into a user's authentication token when they access the modified client. This could lead to unauthorized privilege escalation within the Keycloak realm.

Severity

This bypasses intended security controls, allowing the injected role to be projected into a user\u0027s authentication token when they access the modified client.
