Authenticated object injection via REST metadata unserialization
Published Mar 13, 2026 · Updated Mar 13, 2026
PHP object injection in Crocoblock JetEngine before 3.8.4.1 allows remote authenticated users to inject objects through REST metadata. JetEngine unsafely unserializes attacker-controlled post metadata while building REST API responses, allowing PHP object instantiation. Contributor-level access is required, and resulting file deletion, data disclosure, or code execution requires a POP chain in another plugin or theme.

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?
Compare these published version ranges with your installed build and any vendor patches.
