A vulnerability was found in the WebOb package. WebOb normalizes the HTTP Location header using urlparse and urljoin. If the URL starts with //, urlparse treats the following part as the hostname, and replaces the original request’s hostname. This issue, combined with user interaction, may become a vulnerability.
If the Response class is used, any HTTP Location header (i.e. location) can be rewritten so that it always passes a full URI that includes the hostname to redirect the user to.
