CyberRota Analysis
AI-GeneratedThe Nex Forms – Ultimate Form Builder – Lite plugin for WordPress is vulnerable to arbitrary file deletion due to improper handling of file paths, allowing authenticated users with admin-level access to delete any file on the server, including critical files like wp-config. This vulnerability arises from a lack of validation in the delete_file() AJAX handler, which directly uses user-supplied input without proper sanitization. WordPress site administrators using this plugin should prioritize immediate updates to mitigate potential exploitation.

Original NVD 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.
