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 ConnectWise ScreenConnect. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2026-04-28, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-05-12; treat that as the outer limit, not the target. CISA also lists it as known to be used in ransomware campaigns.
- EPSS 95.4%, percentile 99.9: FIRST’s model estimates a 95.4% 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.
- Needs an account (high (admin)). Exposure depends on who can log in.
- Editorial verdict: Act now. ScreenConnect Auth Bypass CVE-2024-1709 (CVSS 10) — Any on-premises ScreenConnect server still below 23.9.8 should be treated as compromised until proven otherwise; cloud-hosted customers were patched by ConnectWise.
