Crafted URL allows downloading of BLOBs that are not visible to the user

BLOBs stored on custom content types can be accessed through a non-standard URL, bypassing the declared permission check

Anonymous users can use a crafted URL to illegitimately download Files and Images.  Thanks to Karl Johan Kleist who found that this had been incorrectly reported, and let the security team know.
