Summary
The Uncanny Automator plugin for WordPress is affected in all versions through 7.6.1.1. It deserializes untrusted input (CWE-502), which lets authenticated attackers with Subscriber-level access or higher inject a PHP object when a third-party integration plugin such as PeepSo, MailPoet or WPForms is installed and a recipe stores attacker-controlled trigger meta. A POP chain within the plugin then lets attackers delete arbitrary files on the server.

Description from the CNA
The Uncanny Automator – AI + Automation for WordPress | AI Agent, AI Page Builder, Free AI Usage Included plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 7.6.1.1 via deserialization of untrusted input. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject a PHP Object when a third-party integration plugin (such as PeepSo, MailPoet, WPForms, etc) is installed and a recipe is configured that stores attacker-controlled data as trigger meta. The additional presence of a POP chain within Uncanny Automator allows attackers to delete arbitrary files on the server.
