A newer security update for Microsoft Office 2019 for 32-bit editions has shipped since this one: KB5002755 (2026-08-11). For cumulative update families the newer package includes these fixes, so installing that one is usually the shorter path. Verify against your own update rings before you skip this package.
This is a parallel April 2025 package addressing the same seven Office 2019 CVEs as KB5002700, High severity, CVSS 7.8. Microsoft frequently ships more than one KB for the same set of fixes depending on install type, so confirm which one applies to a given deployment method before assuming coverage. None of the seven CVEs is currently in CISA KEV or ransomware-linked.
Do this: Confirm the correct Office 2019 install type and apply KB5002623 accordingly.
