CyberRota Analysis
AI-GeneratedThe LangGraph Python SDK versions 0.1.45 to 0.4.4 contain a vulnerability in the resource-scoped authorization decorators that allows authenticated users to bypass permission checks, potentially enabling unauthorized access to read, update, or delete other users' resources. This flaw primarily affects Python deployments utilizing the specified decorators without independent enforcement of action checks. Organizations using the affected SDK versions should prioritize upgrading to version 0.4.4 to mitigate the risk of unauthorized resource manipulation.

Original NVD Description
LangGraph Python SDK is used to connect to running LangGraph API servers, manage assistants, threads and stream runs from Python applications. From 0.1.45 until 0.4.4, the langgraph-sdk resource-scoped authorization decorators @auth.on.threads, @auth.on.assistants, and @auth.on.crons ignore the actions argument and register the selected handler for every action on the resource. Because that wildcard resource handler is selected before broader fallback handlers, an authenticated user may bypass fallback action, ownership, or permission checks and read, update, or delete another user's resource. Only Python deployments using actions on the affected decorators are vulnerable, and a deployment remains protected when the selected handler independently enforces all required checks for every action it receives. This issue is fixed in version 0.4.4.
