Name of the Vulnerable Software and Affected Versions WHMCS Bridge versions prior to 7.0

Description The WHMCS Bridge plugin for WordPress contains a flaw allowing arbitrary file uploads. This occurs because the connect() function fails to validate file types. Authenticated attackers with Custom-level access or higher can exploit this to upload files to the server, potentially leading to remote code execution.

Recommendations Update the plugin to a version later than 6.9. As a temporary mitigation, restrict access to the connect() function for users with Custom-level permissions.
