How to fix?

Upgrade Debian:11 jetty9 to version 9.4.35-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream jetty9 package and not the jetty9 package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

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.
