Microsoft's Copilot AI Bug Exposes Email Conflicts

View original source

Microsoft has confirmed the presence of a bug in its Copilot AI system that has involuntarily summarized customers’ confidential emails. This issue persisted for several weeks before it was identified and reported by Bleeping Computer.

  • The bug affected email processing from January, allowing Copilot Chat to access sensitive content despite active data loss prevention policies.
  • Copilot Chat is an AI-powered feature available to Microsoft 365 subscribers for integration within Office products like Word, Excel, and PowerPoint.
  • The bug is identifiable in the Microsoft admin center under CW1226324 and specifically mishandled emails marked with a confidential label.
  • Microsoft has begun deploying a correction for this issue starting in February, though exact customer impact remains undisclosed as the company has not commented on the total number affected.

Additionally, there are growing security concerns regarding AI tools' ability to handle sensitive data without risking unauthorized cloud uploads. This issue prompted the European Parliament's IT department to disable AI features on parliamentary devices to mitigate security risks.
