Name of the Vulnerable Software and Affected Versions MW WP Form plugin for WordPress versions up to, and including, 5.0.1

Description The issue is related to insufficient file type validation in the single file upload function, allowing unauthenticated attackers to upload arbitrary files on the affected site's server, which may make remote code execution possible. The MW WP Form plugin is actively installed on more than 200,000 WordPress websites.

Recommendations For versions up to, and including, 5.0.1, update to a version that fixes the insufficient file type validation issue in the single file upload function to prevent arbitrary file uploads. As a temporary workaround, consider disabling the single file upload function until a patch is available.
