Detailsinfo

A vulnerability classified as problematic has been found in webaways Nex Forms Plugin up to 9.2.3. This affects the function delete_file of the component AJAX Handler. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at wordfence.com. This vulnerability is uniquely identified as CVE-2026-15450 since 07/10/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Additional levels of successful authentication are needed for exploitation. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/01/2026). MITRE ATT&CK project uses the attack technique T1006 for this issue.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
