Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The jetty-http Maven package (org.eclipse.jetty) is affected in versions 9.4.0 through before 9.4.60, 10.0.0 through before 10.0.28, 11.0.0 through before 11.0.29, 12.0.0 through before 12.0.33, and 12.1.0 through before 12.1.7. Jetty mishandles CRLF inside quoted strings in chunked transfer encoding extensions, which can let a remote attacker smuggle HTTP requests past a frontend. The fix is to upgrade to 9.4.60, 10.0.28, 11.0.29, 12.0.33, or 12.1.7. The source lists no workaround.
