Senserva AI Opinion for CVE-2026-26114

This is an authenticated remote code execution flaw in on-premises SharePoint Enterprise Server 2016 and SharePoint Server 2019, meaning an attacker with valid credentials can run code on the server itself rather than just reach data. SharePoint farms often run with high-privilege service accounts and connect to internal file shares and SQL, so a compromised front end can pivot deep into the environment. EPSS is 2 percent and it is not in CISA KEV yet, but SharePoint RCEs have a track record of being weaponized once patches reveal the fix.

Do this: Apply the Microsoft SharePoint security update to your 2016 and 2019 farm servers and confirm the post-patch configuration or PSConfig step completed on each server.
