6. Read the research
Varonis Threat Labs found a critical vulnerability in Microsoft Copilot, dubbed CoSnitch, which allows attackers to exfiltrate sensitive data from enterprises without detection. The vulnerability is a result of three separate issues: automatic prompt execution, silent data exfiltration via OAuth connectors, and indirect prompt injection via web summarization. Varonis disclosed the vulnerability to Microsoft in December 2025, and patches were shipped on August 18, 2026.
