HTTP Request Smuggling

mitmproxy is an interactive, SSL/TLS-capable intercepting proxy with a console interface for HTTP/1, HTTP/2, and WebSockets.

Affected versions of this package are vulnerable to HTTP Request Smuggling via another request/response's HTTP message body. While mitmproxy would only see one request, the target server would see multiple requests. A smuggled request is still captured as part of another request's body, but it does not appear in the request list and does not go through the usual mitmproxy event hooks, where users may have implemented custom access control checks or input sanitization.

How to fix HTTP Request Smuggling?

Upgrade mitmproxy to version 8.0.0 or higher.
