Wu said that Velocore has released a security incident investigation report. Today's attack caused a loss of about $6.8 million in ETH. The root cause is a vulnerability in the Balancer-style CPMM pool contract. The internal logic error of the 'velocore__execute()' function of ConstantProductPool. When a user makes an exchange on Velocore, the Vault contract will make an external call to this function to calculate the exchange result. All CPMM pools of Velocore on Linea and zkSyncEra are affected. Telos Velocore has the same vulnerability that has been resolved. In addition, a snapshot of the affected users has been taken and an appropriate compensation plan will be implemented.
