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 1.1%, percentile 66: FIRST’s model estimates a 1.1% chance of exploitation activity in the next 30 days, higher than 66% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes
org.apache.cxf:cxf-rt-transports-jms(Maven) >= 4.2.0, < 4.2.2, fixed in 4.2.2;org.apache.cxf:cxf-rt-transports-jms(Maven) >= 4.1.0, < 4.1.7, fixed in 4.1.7;org.apache.cxf:cxf-rt-transports-jms(Maven) < 3.6.12, fixed in 3.6.12. Check your lockfile, including transitive dependencies.
