Enable Media Replace <= 4.1.7 - Improper Authorization to Authenticated (Author+) Arbitrary Attachment Change via Background Replace

The Enable Media Replace plugin for WordPress is vulnerable to unauthorized modification of data due to an improper capability check on the 'RemoveBackGroundViewController::load' function in all versions up to, and including, 4.1.7. This makes it possible for authenticated attackers, with Author-level access and above, to replace any attachment with a removed background attachment.
