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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-200"],"references":["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","https://www.wordfence.com/threat-intel/vulnerabilities/id/3ad65e10-6f99-421b-abec-ed374769dfcf?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-15758","score":0.0047,"percentile":0.40663,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
