CVE-2025-60082Network attack vector

Authenticated PHP object injection via unsafe deserialization

Published Dec 18, 2025 · Updated Dec 18, 2025

PHP object injection in add-ons.org PDF for WPForms 6.5.0 and earlier allows remote authenticated users to inject serialized objects. The published advisories do not identify the function, parameter, or data flow that deserializes attacker-controlled input. Exploitation requires Subscriber-level access and a separate plugin or theme with a usable POP chain; resulting actions depend on that chain and include file deletion, data disclosure, or code execution.
