A flaw was found in the LangGraph Python SDK. This vulnerability allows a remote attacker with low privileges to manipulate URL paths by providing unsanitized input. This could result in unintended access, modification, or deletion of resources, potentially compromising data confidentiality and integrity. The issue is most significant in systems that directly use untrusted user input for SDK identifier parameters without validation. langgraph: langgraph-sdk: LangGraph Python SDK: Unsafe URL path construction leads to unauthorized resource access A flaw was found in the LangGraph Python SDK. Unsafe URL path construction allows unauthorized resource access when untrusted end-user input is passed directly into SDK identifier parameters. An attacker can craft identifier values containing path traversal sequences to access resources outside the intended scope.
