CVE-2026-15008 uncannyowl CVE debrief
The Uncanny Automator – Easy Automation, Integration, Webhooks & Workflow Builder Plugin for WordPress has a vulnerability that allows unauthenticated attackers to delete arbitrary files on the server. This is due to insufficient file path validation in the fr_token function in all versions up to, and including, 7.3.1.4. The vulnerability can lead to remote code execution when a specific file, such as wp-config.php, is deleted. 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. This vulnerability has a CVSS score of 8.1 and is considered HIGH severity.
