Contributor-level attachment deletion via missing authorization
Published Aug 2, 2026 · Updated Aug 2, 2026
Authorization bypass in eLightUp Meta Box before 5.13.1 allows remote authenticated users to delete other users' media attachments. The ajax_delete_file handler accepts supplied object and attachment IDs, validates only a field-scoped nonce, and invokes wp_delete_attachment without verifying authorization for either object. Contributor-level access and a configured Meta Box file field are required; successful requests permanently remove the attachment record and underlying file.
