SCA: security update for langgraph-checkpoint (GHSA-fjqc-hq36-qh5p)

medium Tenable Cloud Security Plugin ID 443934

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- LangGraph SQLite Checkpoint is an implementation of LangGraph CheckpointSaver that uses SQLite DB (both
sync and async, via aiosqlite). In versions 4.1.0 and prior, the 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 turn result in code execution at checkpoint load time. This is a defense-in-depth
issue. The affected behavior is reachable only when checkpoint bytes at rest in the backing store can be
modified by an unauthorized party. In most deployments that prerequisite already implies a serious
incident; the additional concern is turning "checkpoint-store write access" into code execution in the
application runtime. This issue has been fixed in version 4.1.1. (CVE-2026-48775)

Solution

Update the langgraph-checkpoint library and its related packages to version 4.1.1 or later.
