CVE-2024-11168: Improper validation of IPv6 and IPvFuture addresses

Published Nov 12, 2024

Improper validation of IPv6 and IPvFuture addresses

Other sources

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.
