Deskripsi (NVD)

Xorbits Xoscar through 0.11.2 contains an unauthenticated deserialization vulnerability that allows remote attackers to execute arbitrary code by sending crafted data over the actor-pool TCP channel. Attackers can exploit SocketChannel.recv() passing unvalidated data to cloudpickle.loads(), which triggers pickle __reduce__ gadget execution before message type validation, achieving remote code execution as the server process which commonly runs as root on GPU nodes.
