Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are
vulnerable to an unauthenticated remote code execution. An unauthenticated
remote code execution vulnerability allowed attackers to transfer a
serialized Java SignedObject object to the Jenkins CLI, that would be
deserialized using a new ObjectInputStream, bypassing the existing
blacklist-based protection mechanism. We’re fixing this issue by adding
SignedObject to the blacklist. We’re also backporting the new HTTP CLI
protocol from Jenkins 2.54 to LTS 2.46.2, and deprecating the
remoting-based (i.e. Java serialization) CLI protocol, disabling it by
default.
