Copilot Skips Confidentiality in Outlook Emails
18 Feb
Summary
- Copilot can read and summarize confidential Outlook emails.
- A fix is being rolled out, but the timeline is unclear.
- This exposes sensitive data like contracts and medical info.
Microsoft's Copilot AI assistant has been found to read and summarize emails in Outlook's Sent and Drafts folders, even those marked as confidential. This bypasses a security feature intended to restrict automated tools. Microsoft has acknowledged the issue, labeling it as 'CW1226324,' and is in the process of rolling out a fix.
However, the exact timeline for when all users will receive this correction is currently unknown. The vulnerability is particularly concerning due to the nature of information often marked confidential, such as business contracts, legal correspondence, and personal medical data. Microsoft has not disclosed the number of affected users, stating the scope of impact is under investigation.
