Description Doran Moppert 2018-05-09 07:15:10 UTC 
Sites can bypass security checks on permissions to install lightweight themes by manipulating the `baseURI` property of the theme element. This could allow a malicious site to install a theme without user interaction which could contain offensive or embarrassing images.
