# CVE-2026-10520: Ivanti Sentry OS Command 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 Sentry. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2026-06-11, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-06-14 ; treat that as the outer limit, not the target.
- EPSS 99.9% , percentile 100.0: FIRST’s model estimates a 99.9% chance of exploitation activity in the next 30 days, higher than 100.0% 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.
