Forensic narrative

DEX Velocore experienced a security breach on June 2nd, 2024, resulting in financial losses approximating $6.8 million in ETH. The primary cause of the incident was faulty logic within the velocore__execute() function of the ConstantProductPool. When a user makes a swap on Velocore, the Vault contract makes an external call to this function to calculate the result of the swap. Attack method (per SlowMist): Contract Vulnerability. Reported loss: $ 6,800,000.
