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 Google Chromium. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-05-13, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-06-03; treat that as the outer limit, not the target.
- EPSS 8.3%, percentile 95: FIRST’s model estimates a 8.3% chance of exploitation activity in the next 30 days, higher than 95% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Needs a user to click or open something. Phishing makes that realistic, but it is not wormable.
What it is
