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"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-03T19:25:48.263863Z","id":"CVE-2026-15450","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-03T19:25:59.037Z"}}]}}
