Prior to LangSmith SDK Python 0.8.0 and JS/TS 0.6.0, the LangSmith SDK\u0027s prompt pull methods (pull_prompt / pull_prompt_commit in Python, pullPrompt / pullPromptCommit in JS/TS) fetch and deserialize prompt manifests from the LangSmith Hub. These manifests may contain serialized LangChain objects and model configuration that affect runtime behavior. When pulling a public prompt by owner/name identifier, the manifest content is controlled by an external party, but prior versions of the SDK did not distinguish this from pulling a prompt within the caller\u0027s own organization. This vulnerability is fixed in LangSmith SDK Python 0.8.0 and JS/TS 0.6.0."
