Summary

The ACPT (Premium) plugin for WordPress by Mauro Cassani is affected in all versions up to and including 2.0.66. Its REST API form creation endpoint lacks a capability check, and email templates are rendered by an unsandboxed Twig environment, so injected Twig expressions run on the server. An authenticated attacker with subscriber-level access or higher can execute code on the server.

Description from the CNA

The ACPT (Premium) plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.0.66 via the render function. This is due to missing capability check on the REST API form creation endpoint and unsandboxed Twig environment rendering email templates. This makes it possible for authenticated attackers, with subscriber-level access and above, to execute code on the server. The exploit requires the attacker to first create a form with malicious email_settings via the REST API endpoint, then trigger form submission to execute the injected Twig expressions.
