CVE-2026-74007Network attack vector

Metadata disclosure via unauthenticated AJAX handlers

Published Aug 18, 2026 · Updated Aug 18, 2026

Sensitive data exposure in 3D FlipBook 1.16.20 and earlier allows remote attackers to read flipbook metadata via unauthenticated AJAX requests. The plugin registers nopriv AJAX actions such as fb3d_send_post, fb3d_send_posts_in, and fb3d_send_post_pages that return post meta and serialized page records for an attacker-supplied book ID without capability, post-status, or password checks. Reachability to WordPress admin-ajax.php is sufficient, and the published impact is limited to confidentiality, including metadata tied to non-public or password-protected books.
