A user EOA on BNB Chain (with EIP-7702 delegation) that had set delegated code via an EIP-7702 Type-4 transaction was drained for ~$17.2K. The delegated code included a pancakeV3SwapCallback() function without proper access control. The attacker directly called this callback with crafted calldata, forcing the victim account to transfer its tokens to an attacker-controlled address. The victim had enabled the delegation to support swap-related logic.
