1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2026-19203)

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

CVSSv4: 8.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to inconsistent interpretation of HTTP requests in the HTTP chunk extension parser when processing a crafted chunked HTTP request containing a line feed in a chunk extension. A remote attacker can send a specially crafted chunked HTTP request to perform HTTP request smuggling attacks.

RFC7230 and RFC2616 compliance modes permit the line-feed condition.
