Microsoft Office Bug Exposed Confidential Emails to Copilot AI

Microsoft recently disclosed a significant security bug in its Office ecosystem that allowed the Copilot AI chatbot to read and summarize paying customers' confidential emails. The vulnerability effectively bypassed established data protection and access policies, exposing sensitive information to the AI system. The incident raised immediate and serious concerns about the privacy and security safeguards surrounding integrated AI assistants that have access to corporate data. It highlighted the risks of AI systems inadvertently gaining access to information beyond their intended permissions.
