keycloak-services is vulnerable to Authorization Bypass
43
Medium Risk
This Affects:
keycloak-servicesTL;DR
Under Fine-Grained Admin Permissions v2, the parent group's children listing endpoint does not filter child groups by the caller's per-child view permissions. A delegated admin who can access a parent group can enumerate child groups they are not authorized to view, including names, paths, and custom attributes. The fix applies the per-child view permission filter on that endpoint.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and use Fine-Grained Admin Permissions v2 to restrict which admins can view groups in a hierarchy.
Background info
keycloak-services is vulnerable to Authorization Bypass in versions 26.2.0 - 26.7.0.
How to fix this
Upgrade the org.keycloak:keycloak-services library to the patch version.
