WebOb provides wrappers around the WSGI request environment, and an object to help create WSGI responses. The objects map much of the specified behavior of HTTP, including header parsing and accessors for other standard parts of the environment.
Security Fix(es):
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.(CVE-2024-42353)
