CVE-2026-4347

Name of the Vulnerable Software and Affected Versions MW WP Form plugin for WordPress versions up to and including 5.1.0

Description The MW WP Form plugin for WordPress is susceptible to arbitrary file movement due to inadequate file path validation through the generate user filepath function and the move temp file to upload dir function. This allows unauthenticated attackers to move arbitrary files on the server, potentially leading to remote code execution if a sensitive file, such as wp-config.php, is moved. The vulnerability is exploitable when a file upload field is added to a form and the “Saving inquiry data in database” option is enabled. It affects over 200,000 WordPress sites.

Recommendations Update the MW WP Form plugin to a version later than 5.1.0.
