EtherVista Smart Contract Vulnerability: $18.60K Reported Loss

·Source-attributed incident record

Incident Overview

EtherVista’s liquidity pool was exploited due to an integer overflow in the K-invariant check inside EtherVistaPair.swap(). 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.
