CVE-2026-0687Network attack vector

Author-level gallery publishing via missing capability checks

Published Jan 24, 2026 · Updated Jan 24, 2026

Missing authorization in Meta-box GalleryMeta 3.0.1 and earlier allows remote authenticated users to create and publish galleries. The mb_gallery custom post type lacks a capability check that restricts gallery creation and publication to appropriately privileged roles. Author-level access is required, and the demonstrated consequence is unauthorized gallery-content modification rather than broader site administration.
