Technical details

The Uncanny Automator plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the fr_token function. This flaw, combined with an insecure deserialization vulnerability (CWE-502), allows unauthenticated attackers to supply a malicious serialized payload via a Forminator form submission. The plugin contains a built-in gadget chain in the Action_Helpers_Email __destruct() method, which can be leveraged to delete arbitrary files on the server. Deleting critical files such as wp-config.php can lead to a full site takeover or remote code execution. The attack requires a specific configuration where a Forminator form is connected to an Uncanny Automator recipe set for 'Everyone'.
