SCA: security update for langgraph, langgraph-sdk (GHSA-3fx2-cqw9-xr3c)

medium Tenable Cloud Security Plugin ID 477815

Description

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

 - LangGraph Python SDK is used to connect to running LangGraph API servers, manage assistants, threads and
 stream runs from Python applications. From langgraph-sdk 0.4.0 until 0.4.6, and from langgraph 1.2.3 until
 1.2.14 when RemoteGraph v3 streaming uses an affected langgraph-sdk version, the synchronous and
 asynchronous v3 stream get_tree and _fetch_state helpers interpolate caller-controlled assistant_id and
 thread_id values into authenticated GET request paths without using _quote_path_param. Relative path
 segments can therefore be normalized into another readable path on the configured server while retaining
 authentication headers. This issue is fixed in langgraph-sdk 0.4.6 and langgraph 1.2.14. (CVE-2026-118667)

Solution

Update the langgraph-sdk library and its related packages to version 0.4.6 or later.
