Lifecycle Timeline
1DescriptionCVE.org
A vulnerability was discovered in Keycloak's administrative interface that allows certain administrators to see information about groups they shouldn't have access to. When the new Fine-Grained Admin Permissions (FGAP v2) are turned on, an administrator who is allowed to see a specific "role" can also see a list of all groups assigned to that role. The system fails to check if the administrator has permission to see those specific groups. This could allow a restricted administrator to discover "hidden" groups and see their details, such as internal names and custom settings, which might contain sensitive deployment information.
AnalysisAI
Keycloak's Fine-Grained Admin Permissions v2 (FGAP v2) fails to enforce group-level authorization when a restricted administrator queries role-to-group assignments, exposing group names and custom attributes beyond the admin's intended scope. Restricted admins holding only role-view permission can enumerate all groups assigned to that role, bypassing the group-level access controls that FGAP v2 is designed to enforce. …

Vulnerability AssessmentAI
| Exploitation | FGAP v2 (Fine-Grained Admin Permissions version 2) must be explicitly enabled in the Keycloak realm - this is a non-default, opt-in feature. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 4.3 (Medium) reflects a network-accessible, low-privilege, no-interaction flaw with limited confidentiality impact and no integrity or availability exposure - an accurate characterization for an information-disclosure-only finding. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained a restricted Keycloak administrator credential - one scoped only to role-view permissions within FGAP v2 - sends a query to the Keycloak admin REST API requesting the group membership list for a role they are authorized to view. The response returns all groups assigned to that role without a secondary group-view authorization check, exposing group names, descriptions, and custom attributes. … |
| Remediation | The primary remediation is to apply the patch released by Red Hat, available via the Red Hat Security Advisory at https://access.redhat.com/security/cve/CVE-2026-14613. … Detailed patch versions, workarounds, and compensating controls in full report. |
