This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The wp_kses_post sanitization applied at save time operates only on array leaf values, leaving array keys entirely unsanitized; the injected key is then rendered directly into an id=\"filelist-<KEY>\" HTML attribute without esc_attr() in Redux_Multi_Media::render(), allowing attribute breakout.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6.4,"severity":"medium","source":"CNA: Wordfence","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},{"score":6.4,"severity":"medium","source":"NVD: security@wordfence.com","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1793855898750,"publishedAt":1793854087147,"references":[{"source":"CNA: Wordfence","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/9b3d7dfc-d181-4717-a881-e0d04f047a0b?source=cve"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/redux-framework/trunk/redux-core/inc/extensions/multi_media/multi_media/class-redux-multi-media.php#L112"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/redux-framework/trunk/redux-core/inc/extensions/users/class-redux-extension-users.php#L1022"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/redux-framework/trunk/redux-core/inc/classes/class-redux-helpers.php#L1126"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/changeset/3779521/redux-framework/trunk/redux-core/inc/extensions/multi_media/multi_media/class-redux-multi-media.php"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/redux-framework/trunk/redux-core/inc/classes/class-redux-helpers.php#L1126"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/redux-framework/trunk/redux-core/inc/extensions/multi_media/multi_media/class-redux-multi-media.php#L112"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/redux-framework/trunk/redux-core/inc/extensions/users/class-redux-extension-users.php#L1022"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/changeset/3779521/redux-framework/trunk/redux-core/inc/extensions/multi_media/multi_media/class-redux-multi-media.php"},{"source":"security@wordfence.com","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/9b3d7dfc-d181-4717-a881-e0d04f047a0b?source=cve"}],"remediation":[],"revision":"eaaa8a400db15e0013986106a39de4be2eb86de1d01d61215391cff2b5018d3b","sources":[{"modifiedAt":1793854087147,"name":"CNA: Wordfence","retrievedAt":1793855301881,"url":"https://www.cve.org/CVERecord?id=CVE-2026-104812"},{"modifiedAt":1793855898750,"name":"NVD","retrievedAt":1793859413007,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-104812"}],"ssvc":null,"status":"published","title":"Redux Framework <= 4.5.16 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'multi_media' Field Array Key","updatedAt":1793859413007}
