Should you act?

Normal patch cycle

No exploitation signal; fix it in your next routine update if you are affected. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

  • No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
  • EPSS 0.5%, percentile 42: FIRST’s model estimates a 0.5% chance of exploitation activity in the next 30 days, higher than 42% of all scored CVEs (low). 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.
  • Only applies if your dependency tree includes org.apache.cxf.services.xkms:cxf-services-xkms-x509-repo-ldap (Maven) = 4.2.0, fixed in 4.2.1; org.apache.cxf.services.xkms:cxf-services-xkms-x509-repo-ldap (Maven) >= 4.1.0, < 4.1.6, fixed in 4.1.6; org.apache.cxf.services.xkms:cxf-services-xkms-x509-repo-ldap (Maven) < 3.6.11, fixed in 3.6.11. Check your lockfile, including transitive dependencies.
