Subscriber-level content type modification via missing capability check
Published Dec 4, 2025 · Updated Apr 8, 2026
Authorization bypass in WebDevStudios Custom Post Type UI 1.18.0 and earlier allows remote authenticated users to alter custom post types. The cptui_process_post_type function processes add, edit, and delete requests without checking the caller's required capability. Subscriber-level access is sufficient, although Wordfence describes exploitation as limited to certain request conditions without publishing those conditions.
