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 Kingsoft WPS Office. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-09-03, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-09-24; treat that as the outer limit, not the target.
- EPSS 2.9%, percentile 87: FIRST’s model estimates a 2.9% chance of exploitation activity in the next 30 days, higher than 87% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Needs local access needed. Lower urgency for most teams unless an attacker could already run code on the machine.
