What is CVE-2026-14209?
CVE-2026-14209 is a medium-severity missing authorization vulnerability in Redhat Build of Keycloak, published on 30 Jun 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
A vulnerability was discovered in Keycloak's Admin UI extension that allows certain administrative users to bypass security restrictions. When Fine-Grained Admin Permissions (FGAPv2) are enabled, an administrator who should only be able to search for users (but not view their full details) can use a specific "brute-force-user" endpoint to access a user's full profile. This includes sensitive information and security metadata. The issue occurs because the system fails to check if the administrator has the required "view" permission for that specific user when using this particular search path.
