LangGraph Checkpoint: Unsafe JSON deserialization in checkpoint loading

SummaryLangGraph's JsonPlusSerializer can reconstruct Python objects from JSON checkpoint payloads. Under conditions where someone could modify checkpoint bytes at rest in the backing store, the deserialization path could reconstruct objects beyond what the application expects, which could in tur...

LangGraph checkpoint loading has unsafe msgpack deserialization

LangGraph checkpointers can load msgpack-encoded checkpoints that reconstruct Python objects during deserialization. If an attacker can modify checkpoint data in the backing store for example, after a database compromise or other privileged write access to the persistence layer, they can...
