Microsoft security update released 2026-07-14. Fixes 12 CVEs.
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. For the bigger picture: how the Microsoft patching tools fit together, this month's Patch Tuesday summary, and every update ranked by real-world risk.

Update summary
Senserva AI Opinion for KB5002890
KB5002890 is a Security Update for Microsoft Word 2016 in both 32-bit and 64-bit editions, shipped in the July 2026 Patch Tuesday cycle. The per-update CVE detail is still provisional and Microsoft has not published it yet, but the MSRC release document maps no named zero-days to this update, which lowers the pressure for same-day action. Anyone running Word 2016 as a document handler for external files is the exposed population, since Word patches typically address parsing of attacker-supplied files.
Do this: Stage KB5002890 to a Word 2016 test group now and hold broad deployment until Microsoft publishes the per-update CVE detail to confirm severity.

How to install KB5002890
Any of these paths delivers KB5002890; 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 KB5002890 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 KB5002890, ranked by exploitation.
