CVE-2025-3623: uncanny automator vulnerability

What is known

The Uncanny Automator plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 6.4.0.1 via deserialization of untrusted input in the automator_api_decode_message() function. This makes it possible for unauthenticated to inject a PHP Object. The additional presence of a POP chain allows attackers to delete arbitrary files.

Business impact

Successful exploitation of CVE-2025-3623, a critical vulnerability (CVSS 9.1) affecting uncanny automator, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether uncanny automator is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
