This exploit chain is reachable only on sites where an administrator has created a custom wpForo secondary usergroup with a blank WordPress role and the 'mth' (Manage Themes) capability; on such sites, an attacker can self-register and claim that group via the unguarded wpforo_secondary_groupids[] POST field, bypassing the role-based group filter and gaining theme-management access as a Subscriber.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6.5,"severity":"medium","source":"CNA: Wordfence","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},{"score":6.5,"severity":"medium","source":"NVD: security@wordfence.com","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"}],"modifiedAt":1794046626923,"publishedAt":1794043545421,"references":[{"source":"CNA: Wordfence","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/268f05d4-5f93-4d89-aa7f-c8731599dbc7?source=cve"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.2.2/classes/Actions.php#L2409"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.2.2/classes/Actions.php#L2405"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.2.2/classes/Members.php#L1428"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.2.2/includes/functions.php#L1659"},{"source":"CNA: Wordfence","tags":[],"url":"https://wordpress.org/plugins/wpforo/#developers"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/changeset?reponame=&new=3778162%40wpforo%2Ftags%2F3.2.3&old=3717441%40wpforo%2Ftags%2F3.2.2"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.2.2/classes/Actions.php#L2405"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.2.2/classes/Actions.php#L2409"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.2.2/classes/Members.php#L1428"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.2.2/includes/functions.php#L1659"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/changeset?reponame=&new=3778162%40wpforo%2Ftags%2F3.2.3&old=3717441%40wpforo%2Ftags%2F3.2.2"},{"source":"security@wordfence.com","tags":[],"url":"https://wordpress.org/plugins/wpforo/#developers"},{"source":"security@wordfence.com","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/268f05d4-5f93-4d89-aa7f-c8731599dbc7?source=cve"}],"remediation":[],"revision":"a284569e9798d6990b50230e61320f2a4593389909bc083d46ffec08cc680463","sources":[{"modifiedAt":1794043545421,"name":"CNA: Wordfence","retrievedAt":1794046102559,"url":"https://www.cve.org/CVERecord?id=CVE-2026-110004"},{"modifiedAt":1794046626923,"name":"NVD","retrievedAt":1794053769603,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110004"}],"ssvc":null,"status":"published","title":"wpForo Forum <= 3.2.2 - Authenticated (Subscriber+) Arbitrary File Deletion via Path Traversal via 'theme' Parameter","updatedAt":1794053769603}
