中文标题:
LangChain 代码问题漏洞
英文标题:
LangChain serialization injection vulnerability enables secret extraction
漏洞描述
中文描述:
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 0.3.37之前版本和1.2.3之前版本存在代码问题漏洞，该漏洞源于序列化注入，可能导致反序列化时执行任意代码。
英文描述:
LangChain is a framework for building LLM-powered applications. Prior to @langchain/core versions 0.3.80 and 1.1.8, and prior to langchain versions 0.3.37 and 1.2.3, a serialization injection vulnerability exists in LangChain JS's toJSON() method (and subsequently when string-ifying objects using JSON.stringify(). The method did not escape objects with 'lc' keys when serializing free-form data in kwargs. The 'lc' key is used internally by LangChain to mark serialized objects. When user-controlled data contains this key structure, it is treated as a legitimate LangChain object during deserialization rather than plain user data. This issue has been patched in @langchain/core versions 0.3.80 and 1.1.8, and langchain versions 0.3.37 and 1.2.3
