Name of the Vulnerable Software and Affected Versions Firefox versions prior to 139 Firefox ESR versions prior to 115.24 Firefox ESR versions prior to 128.11

Description The issue arises from insufficient escaping of the ampersand character in the "Copy as cURL" feature. This could allow an attacker to trick a user into executing a command, potentially leading to local code execution on the user's system. This bug only affects Firefox for Windows, with other versions of Firefox being unaffected.

Recommendations For Firefox versions prior to 139, update to version 139 or later. For Firefox ESR versions prior to 115.24, update to version 115.24 or later. For Firefox ESR versions prior to 128.11, update to version 128.11 or later.
