CVE-2024-42353 Information

Description

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.
