When proxy auto-detection is enabled, if a web server serves a Proxy
Auto-Configuration (PAC) file or if a PAC file is loaded locally, this PAC
file can specify that requests to the localhost are to be sent through the
proxy to another server. This behavior is disallowed by default when a
proxy is manually configured, but when enabled could allow for attacks on
services and tools that bind to the localhost for networked behavior if
they are accessed through browsing. This vulnerability affects Firefox <
65.
