CVE-2026-34070
CVE-2026-34070 · LangChain Core has Path Traversal vulnerabilites in legacy `load_prompt` functions
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
LangChain is a framework for building agents and LLM-powered applications. Prior to version 1.2.22, multiple functions in langchain_core.prompts.loading read files from paths embedded in deserialized config dicts without validating against directory traversal or absolute path injection. When an application passes user-influenced prompt configurations to load_prompt() or load_prompt_from_config(), an attacker can read arbitrary files on the host filesystem, constrained only by file-extension checks (.txt for templates, .json/.yaml for examples). This issue has been patched in version 1.2.22.
