Attack profile from CVSS 4.0 · CNA. Fix status from CNA and Red Hat. Impact type from CWE-863.
Summary
Eclipse Jetty jetty-security and jetty-eeN security and servlet modules are affected in 7.6.13 through 9.4.64, 10.0.0 through 10.0.32, 11.0.0 through 11.0.32, 12.0.0 through 12.0.38, and 12.1.0 through 12.1.11. Constraints for HTTP method omission match methods by substring, so a request can bypass them (CWE-863). An unauthenticated remote attacker can exploit this with low complexity, gaining limited confidentiality and integrity impact.

Description from the CNA
In Eclipse Jetty, across various versions of `jetty-security`, and `jetty-eeN-security`, and `jetty-eeN-servlet`, the Jakarta Spec constraints defined as `http-method-omission` can be bypassed by using substrings of the defined HTTP Methods.
