KB5002753 is a Critical security update for Microsoft SharePoint Server 2019, released 2025-07-08. It closes 2 CVEs with a maximum CVSS of 9.8. At least one of them is actively exploited (CISA KEV) and linked to ransomware, so this is a deploy-first update. The most likely of them to be attacked is CVE-2025-53771, which FIRST.org rates at 100% probability of exploitation in the next 30 days.
Update summary
Fixes 2 CVEs. At least one is actively exploited (CISA KEV). Most severe CVSS 9.8 (Critical). EPSS exploit probability up to 100%. One is linked to ransomware. Among the top 5% of tracked Microsoft updates by EPSS exploit probability.
A newer security update for Microsoft SharePoint Enterprise Server 2016 has shipped since this one: KB5002882 (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.
We checked Microsoft's support article for KB5002753 on 2026-08-11 and it lists no known issues. Read the article before broad deployment; Microsoft adds issues as reports come in, and we re-check on every refresh.
Another package addressing the same critical SharePoint pair, CVE-2025-53771 and CVE-2025-53770, this update from the July 8, 2025 cycle covers SharePoint Enterprise Server 2016, SharePoint Server 2019, and Subscription Edition at Critical severity, CVSS 9.8, with a 100 percent EPSS score, CISA KEV confirmation, and documented ransomware use. Given that scale, patching should not wait on change control review.
Do this: Escalate deployment of this update outside normal change windows given confirmed active exploitation and ransomware use.
