Detailsinfo

A vulnerability was found in Keycloak on Red Hat (affected version not known) and classified as problematic. This issue affects some unknown functionality. The manipulation with an unknown input leads to a insufficient granularity of access control vulnerability. Using CWE to declare the problem leads to CWE-1220. The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets. Impacted is confidentiality. The summary by CVE is:

A flaw was found in the Fine-Grained Admin Permissions (FGAP) v2 implementation within Keycloak's administrative services. When FGAP v2 is enabled, the system fails to properly filter child groups based on the caller's specific permissions when requested through a parent group. This allows a delegated administrator to view details of child groups they are not authorized to access directly, including group names, paths, and custom attributes.

The advisory is shared at access.redhat.com. The identification of this vulnerability is CVE-2026-14615 since 07/03/2026. The exploitation is known to be easy. The attack may be initiated remotely. Neither technical details nor an exploit are publicly available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
