Senserva AI Opinion for KB5002621

CVE-2024-38020, Severity Medium at CVSS 6.5, is resolved in this July update for Office 2019 and Microsoft 365 Apps for Enterprise. Microsoft 365 Apps devices on Current Channel typically pick this up automatically, so focus manual verification on Office 2019 perpetual-license machines. At Medium Severity this is routine maintenance rather than an urgent fix.

Do this: Verify Office 2019 perpetual-license machines received this update, since Microsoft 365 Apps devices likely auto-updated already.
