A confused-deputy access-control flaw in New Market Trading's third-party SquidRouterModule let an attacker drain roughly $3.8 million from 88 Gnosis Safe wallets across Ethereum, Base, and Arbitrum.

$54.7M drained from KyberSwap Elastic after a rounding error in concentrated-liquidity math let an attacker trick pools into recognising double the liquidity.
