Vulnerability Title
LangChain: Unsafe deserialization of attacker-controlled LangChain objects through overly broad `load()` allowlists
Vulnerability Description
LangChain is a framework for building agents and LLM-powered applications. Prior to 0.3.85 and 1.3.3, LangChain contains older runtime code paths that deserialize run inputs, run outputs, or other application-controlled payloads using overly broad object allowlists. These paths may call load() with allowed_objects="all". This does not enable arbitrary Python object deserialization, but it does allow any trusted LangChain-serializable object to be revived, which is broader than these runtime paths require. As a result, attacker-supplied LangChain serialized constructor dictionaries may cause trusted runtime paths to instantiate classes with untrusted constructor arguments. This vulnerability is fixed in 0.3.85 and 1.3.3.

Vulnerability Title
LangChain 代码问题漏洞
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 0.3.85之前版本和1.3.3之前版本存在代码问题漏洞,该漏洞源于运行时代码路径使用过于宽泛的对象白名单反序列化运行输入、输出或其他应用控制的有效载荷,允许攻击者提供的LangChain序列化构造函数字典实例化带有不可信构造函数参数的类。
