Probably an extreme case of paranoia on my part, but Domino's should probably close this as a vulnerability, right?
If I knew someone's phone number I could potentially use this to impersonate a delivery driver to gain access to someone (at a residential address or business)...
I mean sure, I could just knock on a door or walk in impersonating someone else... but expecting a pizza delivery is different than ignoring/alerting someone to an unknown solicitor.
OR you could also potentially use it to locate someone based on phone number by following a delivery driver from the local Domino's?
You could also just use it to steal pizza. Just find the contact information of a bunch of people in a nearby condo building and wait at the door and say "Oh is that for John Doe? That's me, I'll take it"
