CVE-2026-2332

CRITICALNVD 9.19.1—
EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.1 under NVD CVSS v3. EPSS exploit probability: 1.3%, top 32% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

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.

EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).
