Description

A flaw was found in LangChain. Multiple functions in `langchain_core.prompts.loading` read files from paths embedded in deserialized configuration dictionaries without validation for 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.
