According to FoxNewsAI, a Microsoft 365 Copilot bug surfaced in enterprise tenants that could surface files and SharePoint content beyond intended scopes during AI-assisted searches and summaries, raising least-privilege and data leakage concerns for regulated industries, as reported by Fox News. According to Fox News, the issue underscores the need to harden Graph permissions, review SharePoint Online inheritance, and tighten sensitivity labels and Data Loss Prevention so Copilot cannot overreach indexed content. According to Fox News, organizations should immediately audit Copilot access logs, restrict Copilot in high-risk workspaces, and implement just-enough-access with Microsoft Purview to mitigate exposure while Microsoft addresses the defect.
