Dolibarr versions 10.0.0 before 24.0.0 fail to perform per-object authorization checks in the Users::getGroups REST API endpoint, allowing authenticated users to retrieve group memberships of other users. Attackers can call GET /users/{id}/groups with arbitrary user identifiers to access group names, entity associations, and private notes across tenant boundaries.
