Senserva AI Opinion for CVE-2025-62203

Like its siblings, this Excel remote code execution flaw pairs desktop exposure (Office 2019, 32-bit and 64-bit) with server exposure (Office Online Server). What keeps it out of the urgent pile is the 1 percent EPSS score and the absence of any confirmed exploitation, but the class is well understood by attackers and cheap to weaponize once details emerge. Severity is High at CVSS 7.8.

Do this: Close this out in the current Office update run and audit for any Office Online Server instances missing recent patches.
