Permission grant via clickjacked popup notification

Published Jun 2, 2023 · Updated May 27, 2025

CVE-2023-32207 in Mozilla Firefox, Firefox ESR, and Thunderbird before their fixed releases allows remote attackers to grant permissions via clickjacking. PopupNotifications omitted a required delay before enabling notification actions, allowing a crafted page to place a click on the permission control. Exploitation requires a user to interact with the deceptive popup; the documented impact is unauthorized permission grants, including location access, rather than direct code execution.
