Description Cathy Hu 2023-05-24 08:52:40 UTC

CVE-2023-32681

Versions of Requests between v2.3.0 and v2.30.0 are vulnerable to potential
forwarding of `Proxy-Authorization` headers to destination servers when
following HTTPS redirects.

When proxies are defined with user info (https://user:pass@proxy:8080), Requests
will construct a `Proxy-Authorization` header that is attached to the request to
authenticate with the proxy.

In cases where Requests receives a redirect response, it previously reattached
the `Proxy-Authorization` header incorrectly, resulting in the value being
sent through the tunneled connection to the destination server. Users who rely on
defining their proxy credentials in the URL are *strongly* encouraged to upgrade
to Requests 2.31.0+ to prevent unintentional leakage and rotate their proxy
credentials once the change has been fully deployed.

Users who do not use a proxy or do not supply their proxy credentials through
the user information portion of their proxy URL are not subject to this
vulnerability.
