Should you act?
Exploited: patch now if you run it
CISA has confirmed exploitation in the wild. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Yes, if you run Omnissa Workspace One UEM. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2026-03-09, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-03-23; treat that as the outer limit, not the target.
- EPSS 99.7%, percentile 100.0: FIRST’s model estimates a 99.7% 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.
