Kerentanan Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') pada langchain core. Skor CVSS 3.1 7.5 (High) menurut github.com.

Deskripsi (NVD)

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.
