Today I noticed that two Avis reservations for someone else are showing up in my TripIt account. I don't see any flight or hotel reservations for this person, so I'm assuming Avis sent the entry in error through their integrated TripIt program. Anyone else seen an error like this? The reservations don't show up in my account on Avis.

Seems like it could be quite a security breach, as I now have the name and reservation number of this other person.
