CertiK: An unaudited smart contract on the Base Chain was attacked, resulting in 55 WETH being lost by users who had interacted with the contract before.

BlockBeats News, October 30th, according to CertiK Alert monitoring, an unverified contract on the Base chain was attacked, resulting in a user who had previously authorized the contract losing 55 WETH (approximately $220,000).

Users need to revoke authorization to the contract address. The contract’s public function uniswapV3SwapCallback() lacks access control, allowing arbitrary execution of transferFrom calls, posing a serious security risk.
