If hyperthreading is not disabled, a timing attack vulnerability exists, similar to previous Spectre attacks. Apple has shipped macOS 10.14.5 with an option to disable hyperthreading in applications running untrusted code in a thread through a new sysctl.

This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7.
