No exploitation is confirmed for the CVEs in this update and the EPSS exploitation probability is currently <1%. That can change: CVEs from past updates regularly get exploited months later, which is why deploying on your normal cadence, without exceptions that linger, is what keeps this one boring.
Most organizations deliver an update like this automatically through Intune update rings, Windows Update for Business, Windows Autopatch, or WSUS; the install section below covers each path.

Update summary
Senserva AI Opinion for KB5002812
KB5002812 patches a single Office flaw (CVE-2025-62552) rated High at CVSS 7.8, affecting Office 2019 in both 32-bit and 64-bit editions plus Microsoft 365 Apps for Enterprise on 32-bit systems. Exploitation odds are currently low (EPSS 1%, not in CISA KEV, no ransomware ties), so this is routine hygiene rather than an emergency. The exposure is broad because it touches standard desktop Office installs, but the client-side nature typically requires a user to open a crafted file.
Do this: Deploy KB5002812 through your normal December patch cycle to all Office 2019 and 32-bit Microsoft 365 Apps for Enterprise endpoints.

How to install KB5002812
Any of these paths delivers KB5002812; most organizations already have one of the first three running:
- Intune update rings (Windows Update for Business): the update flows on each ring's deferral schedule.
- Windows Autopatch: rings, rollout, and pause or rollback are managed for you; exploited updates can be expedited.
- WSUS / Configuration Manager: approve KB5002812 for your device groups and set a deadline.
- Manual: download from the Update Catalog above and install; fine for a handful of machines, unmanageable at any real scale.
After the rollout, verify rather than assume: update compliance reporting in Intune or Autopatch shows which devices actually installed it, and Siemserva reads Intune, Defender, Autopatch, and Azure Update Manager together to show the devices still missing KB5002812, ranked by exploitation.
Common questions about KB5002812
Is KB5002812 urgent?
KB5002812 is rated High. Include it in your normal patch cycle unless your environment raises its priority.
How do I download KB5002812?
From the Microsoft Update Catalog (linked on this page), or let Intune, Windows Update for Business, Windows Autopatch, or WSUS deliver it. The catalog page lists the download for each supported product.
