Overview

Affected versions of this package are vulnerable to Arbitrary Command Injection due to insufficient escaping of the ampersand character in the Copy as cURL feature. An attacker can execute arbitrary code on the user's system by tricking the user into using a maliciously crafted command. This is only exploitable on Firefox for Windows; other versions are unaffected.

Note:

This issue only affects Firefox/Thunderbird for Windows.
