Target Milestone: ---
Classification: Other
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.
