Alchemix is a DeFi protocol that allows for the creation of synthetic tokens that represent the future yield of a deposit. The DeFi lending agreement Alchemix alETH pool is suspected to have a loophole. A flaw in the deployment script of this vault accidentally created additional vaults (which were not supposed to exist) and placed them in the array of vaults. The Alchemist contract accidentally used the incorrect index into this vault array when calculating reward values. This caused transmuter funds (i.e. rewards) to be sent to pay off debts within the alETH vault instead of going to the correct user. With their debts paid off, the users of these vaults were able to withdraw the collateral for their loans without paying off the loans themselves. This resulted in the extraction of $6.5 million from the protocol.
