DescriptionAn authorization bypass vulnerability exists in the Mautic 7 API v2 endpoints (utilizing API Platform). Under certain conditions, roles configured with owner-scope restrictions (such as `viewown` or `editown`) are not properly enforced. This allows low-privilege authenticated API users to bypass ownership-logic controls and access or modify resources belonging to other users.
