WebOb provides objects for HTTP requests and responses. Prior to 1.8.11, Response._make_location_absolute() in src/webob/response.py checks a Location value for a URI scheme or leading double slash before urllib.parse.urljoin() strips leading C0 control characters and spaces.

Configure applications to only allow redirects to trusted, fully-qualified URIs or to strictly allowlist permitted redirect destinations. Reject any redirect target that does not begin with an expected trusted host or a validated relative path, ensuring no leading whitespace or control characters are present.
