Vulnerability in Keycloak's admin services (CVE-2026-14614)
Summary
Vulnerability in Keycloak's admin services (CVE-2026-14614). Risk of unauthorized operations or information disclosure.
Original description
The description as published by the source.
A flaw was found in the ClientResource component of Keycloak's admin services when Fine-Grained Admin Permissions (FGAP) v2 is enabled. This issue allows a delegated administrator, who should only have limited control over specific clients, to attach or remove hidden client scopes that they are not authorized to see or manage. As a result, an attacker could inject unauthorized data or permissions into the security tokens issued to end-users, potentially tricking other applications into granting higher levels of access than intended.
