Administrator-level PHP object injection via unsafe deserialization
Published Jan 19, 2024 · Updated Apr 28, 2026
PHP object injection in ProfilePress 4.3.2 and earlier allows remote authenticated users with administrator access to inject objects. The get_form_meta function deserializes untrusted form metadata without restricting object classes, allowing attacker-supplied serialized objects to instantiate available PHP classes. Exploitation requires administrator-level access and a usable POP chain from another installed plugin or theme; such a chain enables file deletion, sensitive-data access, or code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
