Executive Summary

The WHMCS Bridge plugin for WordPress has a vulnerability that allows authenticated users with Custom-level access or higher to upload arbitrary files to the server. This happens because the connect() function in the plugin does not properly validate the types of files being uploaded in all versions up to and including 6.9.

This lack of file type validation can enable attackers to upload malicious files, potentially leading to remote code execution on the affected server.
