In Jetty 7.2.2 to 9.4.38, 10.0.0.alpha0 to 10.0.1, and 11.0.0.alpha0 to 11.0.1, CPU usage can reach 100% upon receiving a large invalid TLS frame.

CVSS Score
7.5 High
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

This will be resolved in Jetty 9.4.39, 10.0.2, 11.0.2 which we are currently working on releases for.

There is a workaround which requires usage of a custom class which we've detailed in the Security Advisory on GitHub.
