What is CVE-2018-20721?

The vulnerability in Uriparser prior to version 0.9.1 allows for an out-of-bounds read when handling incomplete URIs that feature an IPv6 address with an embedded IPv4 component, such as the address format '//[::44.1'. This can potentially lead to unintended data exposure or program crashes due to improper parsing of the URIs. This issue underscores the need for rigorous validation processes in URI handling to prevent exploitation.
