CVE-2025-32975: Quest KACE Systems Management Appliance…

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 Quest KACE Systems Management Appliance (SMA). CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2026-04-20, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-05-04; treat that as the outer limit, not the target.
EPSS 2.5%, percentile 84: FIRST’s model estimates a 2.5% chance of exploitation activity in the next 30 days, higher than 84% of all scored CVEs (elevated). 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.
