A flaw was found in the Admin REST API of Keycloak, an identity and access management solution. The Admin API fails to verify the intended audience of bearer tokens during authentication. This issue allows an attacker who operates a client within a realm to capture an administrator's access token and reuse it to perform unauthorized administrative actions, potentially leading to full realm compromise.
