Security Alert: Weaponizing Excel Copilot via Indirect Injection

The March 2026 Patch Tuesday update addresses **CVE-2026-26144**, a critical zero-click flaw in **Microsoft Excel's Copilot Agent**. Attackers can exfiltrate sensitive OneDrive data by injecting malicious "autonomous instructions" into unstructured spreadsheet data.

Because the agent is treated as a trusted insider, the exfiltration bypasses traditional **Data Loss Prevention (DLP)** systems. Enterprises are urged to implement "Human-in-the-Loop" gates for all agentic actions involving external networking.
