Microsoft released a security update patching over 50 vulnerabilities, including six actively exploited zero-days affecting Windows Shell, MSHTML, Microsoft Word, Windows Remote Desktop Services, and the Desktop Window Manager. The patches also address critical remote code execution flaws in AI-assisted developer tools like GitHub Copilot and various IDEs, stemming from prompt injection risks. Experts advise applying the updates promptly, testing them in enterprise environments, and maintaining backups due to the active threats.
