| GHSA-m6rx-h84q-8r95 | Moderate | LangChain: MongoDBChatMessageHistory query injection can allow cross-session access## Impact `MongoDBChatMessageHistory` did not enforce the documented string type for session identifiers at runtime. In affected applications, a structured session identifier could be interpreted as a MongoDB query condition rather than as a literal identifier. Applications are affected when they pass untrusted session identifier input to `MongoDBChatMessageHistory` and store multiple users’ histories in the same collection. An attacker who can invoke chat-history operations may be able to read, modify, or delete another user’s stored conversation. Applications that derive the session ident |
