The CvxCrvRewardsLocker contract swaps tokens through the CRV cvxCRV pool. But, it doesnt use any slippage checks. The swap is at risk of being frontrun / sandwiched which will result in a loss of funds.
Since MEV is very prominent I think the chance of that happening is pretty high.
Heres the swap: CvxCrvRewardsLocker.sol#L247-L252.
Use a proper value for minOut instead of 0.
