Kicker: Code execution
An unauthenticated caller can reach deserialization of attacker-controlled data, allowing it to be interpreted as PHP objects. The export does not disclose the endpoint, parameter, deserialization function or a usable gadget chain. File access or code execution depends on reachable application classes and behavior; a complete code-execution chain is not established. Affected versions: <= 2.2.1. The official changelog confirms 2.2.2 as the remediation release based on the matching flaw and version boundary.
