The _sendMessage function in WormholeDepositProcessorL1 does not verify that the msg.value sent with the transaction is sufficient to cover the cost of the Wormhole message fee and the quoted delivery price. This allows users to pay for the cost of the message with any leftover ETH in the WormholeDepositProcessorL1 contract.
Add a check to ensure that msg.value is equal to the sum of wormhole.messageFee() + wormholeRelayer.quoteEVMDeliveryPrice(), as per the Wormhole docs.
