MEDIUM6.5EPSS 0.01%Keycloak: manage-clients permission escalates to full realm admin access
發布日:2026/3/26修改日:2026/4/6
描述
A flaw was found in Keycloak. An administrator with `manage-clients` permission can exploit a misconfiguration where this permission is equivalent to `manage-permissions`. This allows the administrator to escalate privileges and gain control over roles, users, or other administrative functions within the realm. This privilege escalation can occur when admin permissions are enabled at the realm level.
