CVE-2026-15008: Deserialization of untrusted data vulnerability

The Uncanny Automator – Easy Automation, Integration, Webhooks & Workflow Builder Plugin plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the fr_token function in all versions up to, and including, 7.3.1.4. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). Exploitation requires a Forminator form connected to an Uncanny Automator recipe configured for 'Everyone', allowing unauthenticated form submissions to supply the malicious serialized payload; a gadget chain is present within the plugin via the Action_Helpers_Email __destruct() method, meaning no external gadget library is required.
