## Overview

OpenViking debug vector scroll and count endpoints apply only account-level scoping without user-level access controls, allowing authenticated users to read all co-tenant records. Attackers can query these endpoints to retrieve private memories, resources, skills, and secret material belonging to other users in the same account without administrative privileges.
