## Overview

### Description
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.

## Affected packages

- `org.keycloak:keycloak-services < 26.6.4`

## Remediation

Upgrade to a patched release:

- `org.keycloak:keycloak-services 26.6.4`
