Hi,

The following vulnerability was published for jetty9.

CVE-2020-27218[0]:
| In Eclipse Jetty version 9.4.0.RC0 to 9.4.34.v20201102, 10.0.0.alpha0
| to 10.0.0.beta2, and 11.0.0.alpha0 to 11.0.0.beta2, if GZIP request
| body inflation is enabled and requests from different clients are
| multiplexed onto a single connection, and if an attacker can send a
| request with a body that is received entirely but not consumed by the
| application, then a subsequent request on the same connection will see
| that body prepended to its body. The attacker will not see any data
| but may inject data into the body of the subsequent request.
