Vulnerability Title
Improper validation of IPv6 and IPvFuture addresses
Source: CVE Program / CVE List V5
Vulnerability Description
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.
