This could have led to malicious websites storing tracking data without permission.
MEDIUM 6.5EPSS 0.57%
Does this matter?
Lower severity and a low EPSS score (0.57%). Track it; it rarely justifies an emergency change on its own.
Description
When Firefox is configured to block storage of all cookies, it was still possible to store data in localstorage by using an iframe with a source of 'about:blank'. This could have led to malicious websites storing tracking data without permission. This vulnerability affects Firefox < 115.
