Description Siddharth Sharma 2016-04-25 15:09:59 EDT

Mozilla engineer Mark Goodwin discovered that the Firefox Health Report (about:healthreport) accepts certain events from any content document present in the remote-report iframe. If there were another vulnerability that allowed the injection of web content into the Firefox Health Report iframe, this content could change the sharing preferences of a user by firing the appropriate events at its containing page.
