Senserva AI Opinion for CVE-2026-32201

CVE-2026-32201 is a spoofing flaw in on-premises SharePoint (Enterprise Server 2016, Server 2019, and Subscription Edition) rated Medium severity at CVSS 6.5, but CISA confirmed active exploitation and added it to the KEV catalog on 2026-04-14. Spoofing on SharePoint can let an attacker impersonate trusted content or identities in a portal your users already rely on, which is why the confirmed in-the-wild use matters more than the modest score. The 21 percent EPSS reinforces that this is being probed now rather than a theoretical risk.

Do this: Identify every on-premises SharePoint 2016, 2019, and Subscription Edition farm and apply Microsoft's patch for CVE-2026-32201 immediately per the KEV due date.
