An unauthenticated remote attacker can upload arbitrary content into the memory store (write), retrieve stored document content (read), and permanently delete memories belonging to authenticated users (delete) — all without supplying any credentials. The `/api/memories` counterpart correctly enforces authentication, making this an inconsistent and exploitable authentication boundary.
