kpac/script.cpp in KDE kio before 5.32 and kdelibs before 4.14.30 calls the PAC FindProxyForURL function with a full https URL (potentially including Basic Authentication credentials, a query string, or PATH_INFO), which allows remote attackers to obtain sensitive information via a crafted PAC file.
Weakness
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
