LangChain MongoDB: NoSQL Operator Injection in MongoDBSaver.list() leading to cross-tenant data exposure
Vulnerability Description
LangChain MongoDB provides integrations between MongoDB, Atlas, LangChain, and LangGraph. Prior to langgraph-checkpoint-mongodb 0.3.0 and langgraph-store-mongodb 0.4.0, MongoDBSaver.list(), MongoDBSaver.alist(), and MongoDBStore.search() incorporate filter dictionaries into MongoDB queries without recursively rejecting keys prefixed with $. An authenticated caller who controls a filter argument through HTTP query parameters, request body fields, or agent tool arguments can inject MongoDB Query Language operators such as $regex or $where. In a multi-tenant deployment that uses the filter to enforce per-user or per-tenant isolation, injected operators can bypass intended equality filtering and expose other tenants' checkpoint or store data. Filters constructed entirely from trusted server-side values have lower practical risk. This issue is fixed in langgraph-checkpoint-mongodb 0.3.0 and langgraph-store-mongodb 0.4.0.

LangChain MongoDB 输入验证错误漏洞
Vulnerability Description
LangChain MongoDB是LangChain公司的一款面向大语言模型应用的数据库集成工具,支持向量存储、聊天记录持久化与缓存管理。 LangChain MongoDB存在输入验证错误漏洞,该漏洞源于MongoDBSaver.list()、MongoDBSaver.alist()和MongoDBStore.search()将过滤字典合并到MongoDB查询中,未递归拒绝以$开头的键,经过身份验证的调用者可通过HTTP查询参数、请求体字段或代理工具参数控制filter参数并注入$regex或$whe
