CVE-2025-3623: Uncannyowl Uncanny Automator

Critical severity, CVSS 9.1. EPSS: 0.9% chance of exploitation in the next 30 days.

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.

Affected products

• Uncannyowl Uncanny Automator: before 6.4.0.2 (fixed in 6.4.0.2)
