Vulnerability Title
LangChain Core has Path Traversal vulnerabilites in legacy `load_prompt` functions
Vulnerability Description
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.

LangChain 安全漏洞
Vulnerability Description
LangChain是LangChain开源的一个用于开发由大型语言模型 （LLM） 提供支持的应用程序的框架。 LangChain 1.2.22之前版本存在安全漏洞，该漏洞源于langchain_core.prompts.loading中的多个函数从反序列化配置字典中嵌入的路径读取文件时未验证目录遍历或绝对路径注入，可能导致读取主机文件系统上的任意文件。
