HTTP Request Smuggling via Chunked Extension Quoted-String Parsing

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.

CWE-444 Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling')

The product acts as an intermediary HTTP agent (such as a proxy or firewall) in the data flow between two entities such as a client and server, but it does not interpret malformed HTTP requests or responses in ways that are consistent with how the messages will be processed by those entities that are at the ultimate destination.
