This makes it possible for unauthenticated attackers to extract sensitive data including the full metadata payload of password-protected flipbooks — including title, outline, props, and the serialized data blob containing the underlying PDF file's direct URL — bypassing WordPress post-password confidentiality. Flipbook post IDs can be pre-enumerated via the also-unauthenticated fb3d_send_posts AJAX action, requiring no prior knowledge to target specific flipbooks.","publishedAt":"2026-09-15T05:05:54.330Z","updatedAt":"2026-09-17T13:55:34.665Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["iberezansky 3D FlipBook – PDF Embedder, PDF Flipbook Viewer, Flipbook Image Gallery"],"affected":[{"vendor":"iberezansky","product":"3D FlipBook – PDF Embedder, PDF Flipbook Viewer, Flipbook Image Gallery","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.16.20","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/3ad65e10-6f99-421b-abec-ed374769dfcf?source=cve","https://plugins.trac.wordpress.org/browser/interactive-3d-flipbook-powered-physics-engine/trunk/inc/ajax-get.php#L119","https://plugins.trac.wordpress.org/browser/interactive-3d-flipbook-powered-physics-engine/trunk/inc/ajax-get.php#L136","https://plugins.trac.wordpress.org/browser/interactive-3d-flipbook-powered-physics-engine/trunk/inc/ajax-get.php#L142","https://plugins.trac.wordpress.org/changeset?reponame=&old=3661282%40interactive-3d-flipbook-powered-physics-engine&new=3661282%40interactive-3d-flipbook-powered-physics-engine"],"weaknesses":["CWE-200"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15758.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15758","state":"PUBLISHED","datePublished":"2026-09-15T05:05:54.330Z","dateUpdated":"2026-09-17T13:55:34.665Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-14T16:37:00.739Z"},"containers":{"cna":{"title":"3D FlipBook <= 1.16.20 - Unauthenticated Sensitive Information Exposure in 'id' Parameter","descriptions":[{"lang":"en","value":"The 3D FlipBook – PDF Embedder, PDF Flipbook Viewer, Flipbook Image Gallery plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.16.20 via the 'id' parameter.
