Severity:
auctionLength restriction is not strict
Summary
The only restriction to auctionLength is that it can't be 0, but, a low auctionLength can result in a rug-pull of the borrower, as the lender could set a few seconds long auctionLength, which would result in an inability for anyone to participate in the dutch auction, resulting in the lender adquiring the borrower collateral.
