NVD Description

Note: Versions mentioned in the description apply only to the upstream mitmproxy package and not the mitmproxy package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

Tornado is a Python web framework and asynchronous networking library. Prior to 6.5.6, SimpleAsyncHTTPClient shallow-copied redirected requests and removed only the Host header, leaving Authorization, auth_username, auth_password, and auth_mode in place when a redirect changed scheme, host, or port. This issue is fixed in version 6.5.6.
