Multiple security issues were discovered in Firefox. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, gain additional
privileges by escaping the sandbox, or execute arbitrary code.

It was discovered that Firefox allowed PAC files to specify that requests
to localhost are sent through the proxy to another server. If proxy
auto-detection is enabled, an attacker could potentially exploit this to
conduct attacks on local services and tools. (CVE-2018-18506)
