EverBNB is one the BNB reflection token running on Binance Smart Chain. Simply hold tokens and get rewarded in BNB on every transaction. With the auto-claim feature, you will receive BNB automatically in your wallet.
EverBNB.addLiquidity(uint256,uint256) (#1707-1722) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityWallet,block.timestamp) (#1713-1720)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.
EverBNB._transfer(address,address,uint256) (#1528-1620) performs a multiplication on the result of a division:
-fees = amount.mul(totalFees).div(100) (#1593)
