Report #42236
[architecture] Agent leaks sensitive information or context from User A's session into User B's session due to shared memory namespaces.
Scope all memory retrieval and storage with strict, multi-tenant namespace prefixes at the vector DB query/filter level, never relying solely on embedding distance.
Journey Context:
In a multi-user environment, embeddings for similar requests across different users will be close in vector space. If you just query the vector DB globally, User B might get User A's data. Relying on metadata filtering after retrieval is a security risk. The architectural mandate is to enforce tenant isolation via strict namespace or metadata filtering during the vector search itself.
