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.
Unlike the server-rendered Excel bugs in this batch, this one targets the desktop line: Office 2019 in both editions and Microsoft 365 Apps for Enterprise. A user opening a malicious workbook hands the attacker code execution at High Severity, CVSS 7.8. The 1 percent EPSS score and absence of known exploitation make it a standard-cadence patch.
Do this: Verify Microsoft 365 Apps clients are on a current channel build and push the Office 2019 update through your normal ring.
