Requests: Information Leak

Background

Requests is an HTTP library for human beings.

Description

Requests is vulnerable to potentially leaking Proxy-Authorization headers to destination servers, specifically during redirects to an HTTPS origin with authentication credentials encoded into the URL.

Impact

Users’ proxy authentication secrets could be disclosed to parties beyond the used HTTP proxy server.

Workaround

There is no known workaround at this time.

Resolution

All Requests users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-python/requests-2.31.0"
