Senserva AI Opinion for CVE-2026-1281

The earlier of the two 2026 Ivanti EPMM code injection flaws in the KEV catalog, this one has been confirmed exploited since 2026-01-29 and allows unauthenticated remote code execution at Critical CVSS 9.8 with an 81% EPSS score. EPMM servers face the internet by design so mobile devices can check in, which leaves them permanently in the scanning population. Nation-state actors have repeatedly favored this product family.

Do this: Confirm EPMM is on a build that fixes both 2026 code injection flaws and review server logs back to January for exploitation attempts.
