Among WordPress' capabilities are
unfiltered_upload, however I have yet to find any documentation about what specifically they allow or prevent in their filtering.
The only mention I've found on WordPress' site about
This capability is not available to any role by default (including Super Admins). The capability needs to be enabled by defining the following constant:
define( 'ALLOW_UNFILTERED_UPLOADS', true );
With this constant defined, all roles on a single site install can be given the unfiltered_upload capability, but only Super Admins can be given the capability on a Multisite install.
And again, the description doesn't spell out what's permitted and what's filtered out.
Can someone tell me exactly what elements, code, or file types the
unfiltered_upload capabilities allow or prevent?
