Risk summary
Senserva AI Opinion for CVE-2025-59221
A second Word Remote Code Execution bug shares the same affected list, SharePoint Enterprise Server 2016, SharePoint Server 2019, and 32-bit Office 2019, as the earlier Word RCE CVE in this data, but is rated slightly higher at 8.8 CVSS with a similarly low 2 percent EPSS score. Document-triggered RCE bugs like this depend heavily on a user opening a malicious file, so both fixes need to be applied together. No confirmed exploitation or ransomware activity.
Do this: Patch both Word RCE fixes for Office 2019 and the affected SharePoint versions in the same maintenance window.
