This is another build of the same July 8, 2025 SharePoint update line fixing CVE-2025-53771 and CVE-2025-53770 across SharePoint Enterprise Server 2016, SharePoint Server 2019, and Subscription Edition. It shares the same maximum-severity profile as its sibling packages: Critical CVSS 9.8, 100 percent EPSS, confirmed CISA KEV, and ransomware use.
