This is similar to the high vulnerability I submitted, but also shows a similar exploit can be done if a user isnt a whale, and isnt issuing anything.
A user can send a redeem TX and an evil actor can make it so they get almost nothing back during recollateralization. This requires ordering transactions, or just getting very unlucky with the order of your transaction.
UserA redeems and has nothing to show for it!
Evil user only had to buy 1 tokenB (or even less) to steal 100k of their rToken.

Disallow redemptions/issuance during undercollateralization
