CVE-2026-25363Public exploitNetwork attack vector

Unauthorized gallery-detail changes via unchecked AJAX handlers

Published Feb 19, 2026 · Updated Feb 19, 2026

Missing authorization in FooPlugins FooGallery 3.1.11 and earlier allows remote authenticated users to change gallery details via admin AJAX. The ajax_save_gallery_details() handler verifies a request nonce but does not confirm edit_post capability for the supplied album and gallery IDs. Contributor-level access and a valid admin nonce are sufficient to alter details for album and gallery posts the account cannot edit.
