Inconsistent interpretation of HTTP requests in Jetty - CVE-2026-2332

Vulnerability identifier: #VU125866

CSH Severity: Medium

CVSS v4: 9.1 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-2332

CWE-ID: CWE-444

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to inject arbitrary HTTP requests.

The vulnerability exists due to inconsistent interpretation of HTTP requests in the chunked transfer encoding extension parser when parsing quoted strings in HTTP/1.1 chunked transfer encoding extension values. A remote attacker can send a specially crafted chunked HTTP request to inject arbitrary HTTP requests.

The issue occurs because CRLF sequences inside quoted strings are treated as chunk header terminators instead of parsing errors.
