Risk summary
Not in the CISA KEV catalog. EPSS exploit probability <1%. CVSS 7.8 (High).
This CVE is among the lower half of tracked Microsoft CVEs by EPSS exploit probability.
One of several Excel remote code execution flaws patched in the same wave, affecting Office 2019 and Microsoft 365 Apps for Enterprise. High Severity (CVSS 7.8), 1 percent EPSS, and the usual precondition: a user opens a crafted spreadsheet. The volume of Excel parsing bugs in a single cycle is itself the signal; the file format remains a rich hunting ground for attackers.
Do this: Confirm Microsoft 365 Apps update rings are current and chase any Office 2019 machines pinned to old builds.
