Vulnerability Just prior to launch a security researcher discovered a flaw in the PermitAndDepositDai contract. This flaw would have allowed an attacker to front-run the "deposit" transaction and take the deposited amount. This would have affected any new deposits to the system.
Mitigation References to the contract were removed from the user interface, and a fix was immediately deployed to mainnet and published via NPM.
