The ‘Copy as cURL’ feature of Devtools’ network tab did not properly escape
the HTTP method of a request, which can be controlled by the website. If a
user used the ‘Copy as Curl’ feature and pasted the command into a
terminal, it could have resulted in command injection and arbitrary command
execution. This vulnerability affects Thunderbird < 68.6, Firefox < 74,
Firefox < ESR68.6, and Firefox ESR < 68.6.
