PermitAndDepositDai Contract: Unrestricted Sender

Severity: Medium / High Date: Thursday, October 22nd, 2020 Reporter: Kevin Foesenek Payout: $20,000 USD of WETH (transaction)
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.
