Description Huzaifa S. Sidhpurwala 2015-12-15 03:47:45 EST
Security researcher Abdulrahman Alqabandi reported that when a data: URI is parsed, the hash ('#') symbol is incorrectly handled, allowing for spoofing attacks. This issue could result in the wrong URI being displayed as a location, which can mislead users to believe they are on a different site than the one loaded.
