Sensitive Information in Resource Not Removed Before Reuse
In Eclipse Jetty version 9.4.0.RC0 to 9.4.34.v20201102, 10.0.0.alpha0 to 10.0.0.beta3, and 11.0.0.alpha0 to 11.0.0.beta3, if GZIP request body inflation is enabled and requests from different clients are multiplexed onto a single erconnection, 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.
CWE-226 - Sensitive Information in Resource Not Removed Before Reuse
The product releases a resource such as memory or a file so that it can be made available for reuse, but it does not clear or "zeroize" the information contained in the resource before the product performs a critical state transition or makes the resource available for reuse by other entities.
