maintainerLangChain AI

LangGraph Checkpoint provides the persistence layer for LangGraph agent state, enabling checkpointing and resumption of long-running agent workflows. It defines the checkpoint schema and base classes that backend-specific packages (Postgres, Redis, SQLite) implement. Any deployment using durable agents depends on this package.

attack surface

Why this package is monitored

Checkpointing packages serialize and deserialize the full agent state, including memory, retrieved documents, and tool outputs. A backdoored serializer can inject data into restored checkpoints or exfiltrate the entire conversation history written to persistent storage.
