This is due to the delete_file() AJAX handler retrieving a file path from the database and passing it directly to unlink() with no validation (no realpath(), basename(), or allowlist check), combined with the insert_record() AJAX handler that lets the same authenticated user store an arbitrary value in the target 'location' column (wp_kses() only strips HTML tags and does not neutralize path traversal or absolute paths). This makes it possible for authenticated attackers, with admin-level access and above, to delete arbitrary files on the affected site's server, including wp-config. When the plugin's user-level option is configured to something else, this may be exploitable with lower privileges."}], "title": "NEX-Forms <= 9.2.3 - Authenticated (Admin+) Arbitrary File Deletion via Path Traversal via 'location' Parameter", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/bb5c8cb3-df67-4f2c-869a-48e34f5619ff?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/nex-forms-express-wp-form-builder/tags/9.2.3/includes/classes/class.db.php#L805"}, {"url": "https://plugins.trac.wordpress.org/browser/nex-forms-express-wp-form-builder/tags/9.2.3/includes/classes/class.db.php#L269"}, {"url": "https://plugins.trac.wordpress.org/browser/nex-forms-express-wp-form-builder/tags/9.2.3/includes/classes/class.db.php#L273"}, {"url": "https://plugins.trac.wordpress.org/changeset?reponame=&old=3625615%40nex-forms-express-wp-form-builder&new=3625615%40nex-forms-express-wp-form-builder"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')", "cweId": "CWE-22", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H", "baseScore": 8.1, "baseSeverity": "HIGH"}}], "credits": [{"lang": "en", "type": "finder", "value": "Wordfence PRISM"}], "timeline": [{"time": "2026-07-10T19:42:41.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-07-31T19:42:18.000Z", "lang": "en", "value": "Disclosed"}]}}}
