Unauthenticated information disclosure via command injection
Published May 7, 2026 · Updated May 7, 2026
Command injection in Microsoft Copilot Chat in Microsoft Edge allows remote attackers to disclose information over a network. Microsoft has not disclosed the command-processing locus or how attacker-controlled elements reach an insufficiently neutralized command. No privileges or user interaction are required; the reported consequence is information disclosure from an exclusively hosted service, not code execution or service interruption.
