{"id":"CVE-2026-76010","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-76010","summary":"The Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 4.4.1 via the render_image…","details":"The Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 4.4.1 via the render_image function. 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.","published":"2026-10-31T10:16:38.547","modified":"2026-10-31T10:16:38.547","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/nextgen-gallery/tags/4.3.0/src/DataStorage/Manager.php#L1226"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/nextgen-gallery/tags/4.3.0/src/DataStorage/Manager.php#L2373"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/nextgen-gallery/tags/4.3.0/src/DataStorage/Manager.php#L2951"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/nextgen-gallery/tags/4.3.0/src/DynamicThumbnails/Controller.php#L33"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/nextgen-gallery/tags/4.3.0/src/XMLRPC/Controller.php#L289"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/nextgen-gallery/tags/4.3.0/src/XMLRPC/Controller.php#L69"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset/3699076/nextgen-gallery/trunk/src/DataStorage/Manager.php"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/36dcde20-0af2-4b8b-8637-9a070dffa8a1?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-31T10:16:38.547"}}
