漏洞描述
WordPress 3D FlipBook - PDF Flipbook Viewer, Flipbook Image Gallery plugin versions <= 1.16.17 contain a missing authorization vulnerability in multiple AJAX endpoints. The fb3d_send_posts_in, fb3d_send_post_pages, fb3d_send_posts_in_pages, fb3d_send_posts_in_first_page, and fb3d_send_post_first_page handlers are registered with wp_ajax_nopriv hooks but fail to verify the post status of requested flipbook entries. This allows unauthenticated attackers to retrieve full metadata, PDF URLs, and configuration data of private, draft, and password-protected flipbook posts.
