Overview

Affected versions of this package are vulnerable to Deserialization of Untrusted Data. If a server can deserialize objects from an untrusted source, it is possible to craft a serialized object that runs arbitrary code on deserialization.

Note:

The attacker would likely need to be in a position with elevated trust in order to pass a malicious payload and the attack depends on conditions that are not entirely under his control.
