The MW WP Form plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient file type validation in the '_single_file_upload' function in versions up to, and including, 5.0.1. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.

Unrestricted upload of file with dangerous type exists in MW WP Form versions v4.4.2 and earlier, which may allow a remote unauthenticated attacker to upload an arbitrary file.

Directory traversal vulnerability in MW WP Form versions v4.4.2 and earlier allows a remote unauthenticated attacker to alter the website or cause a denial-of-service (DoS) condition, and obtain sensitive information depending on settings.
