CVE-2025-11143: Eclipse Jetty

Medium severity, CVSS 6.5. EPSS: 0.2% chance of exploitation in the next 30 days.

The Jetty URI parser has some key differences to other common parsers when evaluating invalid or unusual URIs. Differential parsing of URIs in systems using multiple components may result in security by-pass. For example a component that enforces a black list may interpret the URIs differently from one that generates a response. At the very least, differential parsing may divulge implementation details.

Affected products

• Eclipse Jetty: from 9.4.0, up to and including 9.4.58; from 10.0.0, up to and including 10.0.26; from 11.0.0, up to and including 11.0.26; from 12.0.0, before 12.0.31 (fixed in 12.0.31); from 12.1.0, before 12.1.5 (fixed in 12.1.5)
