CVE-2026-67528 updated by NVD
Summary
OpenProject is open-source, web-based project management software. Prior to 17.6.0, GET /api/v3/custom_options/:id resolved CustomOption records by global numeric id and allowed UserCustomField and GroupCustomField options without checking visible(current_user), so authenticated non-admin users could enumerate sequential custom option ids and read labels belonging to admin_only user or group custom fields. This issue is fixed in 17.6.0.
