NCSC-2026-0289 [1.01] [H/H] Kwetsbaarheden verholpen in Microsoft Exchange server

Microsoft patched multiple vulnerabilities in Exchange Server that could enable denial of service, privilege escalation, remote code execution (RCE), and unauthorized access to sensitive data. Proof-of-concept code has been published for CVE-2026-62911, a CVSS 8.0 unauthenticated RCE that allows attackers to access mailboxes and pivot further into victim networks.

Why it matters: Exchange Server administrators must prioritize patching CVE-2026-62911 immediately, as unauthenticated RCE with public exploit code poses direct risk to email systems and lateral movement paths.
