Rapid7 disclosed a SharePoint chain built with heavy AI-agent help that combines July’s authentication bypass CVE-2026-55040 with August’s RCE CVE-2026-63520 for unauthenticated code execution. It took about 120 hours over 24 days.

Why it matters: The total matters less than the one bug already in use.
Recommended action: Track the AFD.sys fix as its own deployment metric.
