Hi,

The following vulnerability was published for mitmproxy.

CVE-2022-24766[0]:
| mitmproxy is an interactive, SSL/TLS-capable intercepting proxy. In
| mitmproxy 7.0.4 and below, a malicious client or server is able to
| perform HTTP request smuggling attacks through mitmproxy. This means
| that a malicious client/server could smuggle a request/response
| through mitmproxy as part of 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. Unless mitmproxy is used to protect an HTTP/1 service,
| no action is required. The vulnerability has been fixed in mitmproxy
| 8.0.0 and above. There are currently no known workarounds.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
