CVE-2018-5116

Priority
Medium
Description
WebExtensions with the "ActiveTab" permission are able to access frames
hosted within the active tab even if the frames are cross-origin. Malicious
extensions can inject frames from arbitrary origins into the loaded page
and then interact with them, bypassing same-origin user expectations with
this permission. This vulnerability affects Firefox < 58.
