Official description
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.

The underlying weakness: Deserialization of Untrusted Data
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
How developers prevent this class of flaw
- If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
- When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.
- Explicitly define a final object() to prevent deserialization.
