Description

In Eclipse Jetty, the HTTP/1.1 parser is vulnerable to request smuggling when chunk extensions are used, similar to the "funky chunks" techniques outlined here: * https://w4ke.info/2025/06/18/funky-chunks.html * https://w4ke.info/2025/10/29/funky-chunks-2.html Jetty terminates chunk extension parsing at \r\n inside quoted strings instead of treating this as an error. POST / HTTP/1.1 Host: localhost Transfer-Encoding: chunked 1;ext="val X 0 GET /smuggled HTTP/1.1 ... Note how the chunk extension does not close the double quotes, and it is able to inject a smuggled request.

Affected configurations

• eclipse jetty (>= 9.4.0 < 9.4.60) • eclipse jetty (>= 10.0.0 < 10.0.28) • eclipse jetty (>= 11.0.0 < 11.0.28) • eclipse jetty (>= 12.0.0 < 12.0.33) • eclipse jetty (>= 12.1.0 < 12.1.7)
