{"id":"CVE-2026-110004","published":"2026-11-07T10:17:06.780","lastModified":"2026-11-08T19:17:33.523","description":"The wpForo Forum plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the theme_delete function in all versions up to, and including, 3.2.2 This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). 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.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-22"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.2.2/classes/Actions.php#L2405","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.2.2/classes/Actions.php#L2409","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.2.2/classes/Members.php#L1428","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.2.2/includes/functions.php#L1659","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&new=3778162%40wpforo%2Ftags%2F3.2.3&old=3717441%40wpforo%2Ftags%2F3.2.2","tags":[]},{"url":"https://wordpress.org/plugins/wpforo/#developers","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/268f05d4-5f93-4d89-aa7f-c8731599dbc7?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
