This is due to unrestricted mass assignment of caller-supplied meta_data keys onto the image model combined with missing realpath containment in path construction and a bypassable signature check on the public image delivery route. This makes it possible for authenticated attackers, with custom-level access and above, to execute code on the server. Exploitation requires the authenticated attacker to own at least one NextGEN gallery — a condition that can be satisfied by any Subscriber who was ever granted the 'NextGEN Manage gallery' capability, and that access is retained indefinitely due to the stored gallery-author equality fallback in _can_manage_gallery() even after the capability is revoked.","epss":{"date":"2026-11-02","percentile":0.55694,"score":0.00772},"exploits":[],"kev":null,"metrics":[{"score":8.8,"severity":"high","source":"CNA: Wordfence","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793630056619,"publishedAt":1793438965701,"references":[{"source":"CNA: Wordfence","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/36dcde20-0af2-4b8b-8637-9a070dffa8a1?source=cve"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/nextgen-gallery/tags/4.3.0/src/DataStorage/Manager.php#L2373"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/nextgen-gallery/tags/4.3.0/src/XMLRPC/Controller.php#L289"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/nextgen-gallery/tags/4.3.0/src/DataStorage/Manager.php#L1226"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/nextgen-gallery/tags/4.3.0/src/DynamicThumbnails/Controller.php#L33"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/nextgen-gallery/tags/4.3.0/src/XMLRPC/Controller.php#L69"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/nextgen-gallery/tags/4.3.0/src/DataStorage/Manager.php#L2951"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/changeset/3699076/nextgen-gallery/trunk/src/DataStorage/Manager.php"}],"remediation":[],"revision":"3a75eee1ec88a6996387cc646f434de503274dc47b81db82c846a107d044660e","sources":[{"modifiedAt":1793630056619,"name":"CNA: Wordfence","retrievedAt":1793632154535,"url":"https://www.cve.org/CVERecord?id=CVE-2026-76010"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793632158590,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-76010"}],"ssvc":{"assessedAt":1793630048237,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"total"},"status":"published","title":"Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery <= 4.4.1 - Authenticated (Custom+) Remote Code Execution via XML-RPC 'meta_data' Mass Assignment and Path Traversal","updatedAt":1793632158590}
