Rouille 0.3.3 - 3.6.2 HTTP Request Smuggling via proxy Header Injection

Published Jul 28, 2026 · Updated Jul 28, 2026 · Assigned by VulnCheck

Vendor: tomaka Product: rouille Package: rust-rouille Ecosystem: Debian

Description

Rouille 0.3.3 through 3.6.2 contains an HTTP request smuggling vulnerability that allows remote attackers to bypass access controls by injecting bare line feed characters (0x0A) into client-supplied request header values that are copied verbatim to upstream connections without validation. Attackers can craft a header value containing a complete additional HTTP request that is interpreted as a separate request by backends such as Go net/http and Python http.server, causing the backend to process a smuggled request with attacker-chosen method, path, and headers that bypasses the rouille handler's access control logic.
