Name of the Vulnerable Software and Affected Versions Onyx Enterprise Edition version 0.27.0

Description An authorization bypass exists in the update user group function within onyx-dot-app Onyx Enterprise Edition. This allows remote authenticated attackers to modify arbitrary user groups by sending crafted PATCH requests to the /api/manage/admin/user-group/id endpoint. The issue bypasses intended curator-group assignment checks.

Recommendations As a temporary workaround, consider restricting access to the /api/manage/admin/user-group/id endpoint until a patch is available.
