8) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2026-2332)

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

CVSSv4: 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/E:U/U:Green

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.

9) Improper input validation (CVE-ID: CVE-2026-46839)

CWE-ID: CWE-20 - Improper input validation
