[ContractVulnerability] SynapLogic Contract Exploit Leads to Significant Losses

A vulnerability in the SynapLogic contract has resulted in substantial financial losses. According to PANews, BlockSec Alert reported that the contract's swapExactTokensForETHSupportingFeeOnTransferTokens function lacked essential parameter verification. This oversight allowed attackers to manipulate the 'whitelist' logic and designate any address for profit. Additionally, the contract failed to verify whether the total distribution of native tokens exceeded the actual payment, enabling attackers to withdraw excess native tokens and simultaneously receive newly minted SYP tokens. This exploit has led to an estimated loss of approximately $186,000.
