漏洞描述

An external contributor, @iczc, discovered a way to mint arbitrary tokens due to the possibility to have two different states not in sync during the execution of a transaction. The exploit is based on the fact that to sync the Cosmos SDK state and the EVM one, we rely on the stateDB.Commit() method. When we call this method, we iterate though all the dirtyStorage and, if and only if it is different than the originStorage, we set the new state. Setting the new state means we update the Cosmos SDK KVStore.
