Description Huzaifa S. Sidhpurwala 2015-12-15 08:34:26 UTC 
Security researcher cgvwzq reported that it is possible to read cross-origin URLs following a redirect if perfomance.getEntries() is used along with an iframe to host a page. Navigating back in history through script, content is pulled from the browser cache for the redirected location instead of going to the original location. This is a same-origin policy violation and could allow for data theft.

This issue affects other browsers as well and is not limited to Mozilla products.
