DescriptionThe ARForms plugin for WordPress is vulnerable to arbitrary file upload in all versions up to, and including, 7.2.4 via its form file-upload handler. The name of the stored file is taken from an attacker-controlled request header and is not adequately restricted to safe file types, and the plugin's file-type and content-safety checks can be evaded, allowing files that contain executable PHP code to be written to a publicly accessible directory. This makes it possible for unauthenticated attackers to upload malicious files to the affected site's server, which may make remote code execution possible. Exploitation requires a published form containing a File field to be publicly accessible on the site.
