Incident Overview
Both reserves are uint112, so their product can wrap around and the check can pass even when the real reserve product drops sharply. The attacker registered a self-controlled contract as an authorized router and ran two crafted swaps to drain WETH and VISTA, with a loss of about $18,600.
