## Overview

A flaw was found in Keycloak. A highly privileged user with `manage-clients` permission can exploit this vulnerability by injecting a hardcoded role mapper into any client. This action allows the user to bypass existing scope restrictions and inject the `realm-admin` role into generated tokens, resulting in privilege escalation and full administrative access to the realm.

## Affected

- `rhbk/keycloak-operator-bundle (all versions)`
- `rhbk/keycloak-rhel9 (all versions)`
- `rhbk/keycloak-rhel9-operator (all versions)`
- `rhbk/keycloak-rhel9`
- `build_of_keycloak_26.6.5`
