There absolutely is a known MITM attack vector when using a vocab served
over HTTP for commerce. :)

If schema.org defines the concept of a 'source' and 'destination' for
a financial transaction an attacker could poison a downstream DNS such
that the retrieved vocab document switches source and destination, thus
giving attackers the ability to suck funds out of your financial accounts.

This is one of the reasons that the PaySwarm vocabs are served from
https://w3id.org/ and the reason that we serve those vocabs using the
HTTP Strict Transport Security (HSTS) HTTP headers.
