CVE-2024-2611Public exploitNetwork attack vector

Permission grant via pointer-lock input-delay bypass

Published Mar 19, 2024 · Updated Feb 13, 2025

Clickjacking in Mozilla Firefox before 124, Firefox ESR before 115.9, and Thunderbird before 115.9 allows remote attackers to obtain permissions. PopupNotifications fails to extend the permission-button input delay while pointer lock redirects repeated clicks, letting a page align those clicks with a visible prompt. A user must open the malicious page and keep clicking; successful exploitation grants the requested site permission, while email reading alone does not expose Thunderbird because scripting is disabled.
