AI agents call remember_admin_search_across_users to retrieve information from Remember without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries data (search operation) without modifying, deleting, or executing anything. It is clearly a Read action. Severity is high rather than low because it operates across multiple user tenants in a multi-tenant system, creating significant blast radius if misused by an agent that could access sensitive memories belonging to other users.
From the tool's definition Tool name and description indicate 'Search memories across multiple user tenants' with 'Results include which user each memory belongs to.' The verb 'search' is a read operation with no modification.
