CVE-2026-14614 Red Hat CVE debrief
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. The vulnerability affects Keycloak deployments with FGAP v2 enabled and involves unauthorized access to client scopes. The issue has a CVSS score of 5.4 and is classified as MEDIUM severity.
