[Security-announce][CVE-2024-11168] Improper validation of IPv6 and IPvFuture addresses

There is a MEDIUM severity vulnerability affecting CPython.

The urllib.parse.urlsplit() and urlparse() functions improperly validated bracketed hosts ([]), allowing hosts that weren't IPv6 or IPvFuture. This behavior was not conformant to RFC 3986 and potentially enabled SSRF if a URL is processed by more than one URL parser.
