Microsoft issued an emergency patch for a critical vulnerability in its SharePoint server software after hackers launched global attacks targeting businesses and U.S. federal agencies. The zero-day exploit allowed access to file systems and code execution. The patch addresses SharePoint Subscription Edition and SharePoint 2019, with a fix for SharePoint 2016 pending. CISA confirmed the attacks and advised disconnecting affected servers until updated. This follows recent high-profile breaches involving Microsoft software.
