What is CVE-2026-97177?

A vulnerability exists in the Keycloak Admin REST API where the user update mechanism fails to properly verify password reset permissions when Fine-Grained Admin Permissions are enabled. This oversight allows a delegated administrator, who should not have access to reset user passwords, to alter a user’s credentials, potentially granting them unauthorized access to user accounts.
