# CVE-2026-1281: Ivanti Endpoint Manager Mobile (EPMM) Code Injection Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Ivanti Endpoint Manager Mobile (EPMM). CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2026-01-29, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-02-01 ; treat that as the outer limit, not the target.
- EPSS 98.7% , percentile 99.9: FIRST’s model estimates a 98.7% chance of exploitation activity in the next 30 days, higher than 99.9% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Editorial verdict: Act now. Ivanti EPMM Zero-Day RCE: CVE-2026-1281 and CVE-2026-1340 — On-premises Ivanti EPMM was open to unauthenticated remote command execution, exploited before disclosure and with a public PoC a day later; patch, confirm the RPM survived any later upgrade, and hunt for compromise.
