Microsoft has moved MDASH (Multi-model Agentic Scanning Harness) into expanded enterprise preview, integrating AI-agent-based security triage across Microsoft Defender, GitHub Advanced Security, Microsoft Purview, and the Agent 365 SDK. No CVE is associated with this item. The primary security concern is governance: AI agents performing triage in production security pipelines introduce new attack surfaces — agent identities, sandbox escape paths, and prompt injection risks — that must be governed before production adoption.
