CVE-2021-24000
A race condition with requestPointerLock() and setTimeout() could have resulted in a user interacting with one tab when they believed they were on a separate tab. In conjunction with certain elements (such as <input type="file">) this could have led to an attack where a user was confused about the origin of the webpage and potentially disclosed information they did not intend to. This vulnerability affects Firefox < 88. Date published : 2021-06-24 https://bugzilla.mozilla.org/show_bug.cgi?id=1694698
