    Outlook CVE-2026-100208: integer overflow that can become network RCE. Microsoft scores it 7.5 High. Needs a user click, high complexity, no privileges. NVD has no patch or version list yet. Until Microsoft maps builds, treat surprise calendar invites and attachment opens as high-risk. Same for GCC and commercial tenants.
