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 Apple Multiple Products. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-11-21, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-12-12; treat that as the outer limit, not the target.
  • EPSS 10.2%, percentile 96: FIRST’s model estimates a 10.2% chance of exploitation activity in the next 30 days, higher than 96% of all scored CVEs (very high). EPSS is a probability, not a verdict.
  • Needs a user to click or open something. Phishing makes that realistic, but it is not wormable.
