This CVE is among the top half of tracked Microsoft CVEs by EPSS exploit probability.
CVE-2026-97010 is a remote code execution flaw in Microsoft Excel, listed against Office Online Server, Microsoft Office 365 for Mac, and Microsoft Office LTSC for Mac 2021. What stands out is the mix of a server product and two Mac desktop builds, so exposure spans both an internal Office Online Server deployment and any Mac fleet running those Office versions. Severity is High (CVSS 8.8), but the EPSS exploit probability is only 1%, it is not in CISA KEV, and no ransomware use is known, so this looks like a prioritized patch rather than an emergency.
Do this: Inventory where Office Online Server and the affected Office for Mac builds are deployed, then apply Microsoft's update to Office Online Server first since it is shared server infrastructure, followed by the Mac clients.
