Reentrancy in `withdraw` function
The `withdraw` function doesn't reset the `bid_values` to 0 after the withdraw. That means the bidder can call multiple time the `withdraw` function and receive the whole balance of the protocol.
The `highest_bidder` can withdraw the value of all bids
The `withdraw` function allows the participants to receive back the value of all their unsuccessful bids. The problem is that the winner of the auction will receive all bids including the `highest_bid` that should be paid to the NFT owner.
