WebOb provides objects for HTTP requests and responses. When WebOb
normalizes the HTTP Location header to include the request hostname, it
does so by parsing the URL that the user is to be redirected to with
Python’s urlparse, and joining it to the base URL. urlparse however
treats a // at the start of a string as a URI without a scheme, and then
treats the next part as the hostname. urljoin will then use that hostname
from the second part as the hostname replacing the original one from the
request. This vulnerability is patched in WebOb version 1.8.8.
