CVE-2026-15450 NEX-Forms <= 9.2.3 - Authenticated (Admin+) Arbitrary File Deletion via Path Traversal via 'location' Parameter

What is CVE-2026-15450?

CVE-2026-15450 is a high-severity path traversal vulnerability in webaways NEX-Forms – Ultimate Forms Plugin for WordPress, published on 1 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

The Nex Forms – Ultimate Form Builder – Lite plugin for WordPress is vulnerable to arbitrary file deletion via path traversal in versions up to, and including, 9.2.3. 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.

Weakness: CWE-22
