WKG [Wukong] Token

WKG.addLiquidity(uint256,uint256) (#1020-1034) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: bnbAmount}(address(this),tokenAmount,0,0,deadAddress,block.timestamp) (#1026-1033)
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.

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

Contract ownership is not renounced (belongs to a wallet)

WKG.totalFees (#527) is set pre-construction with a non-constant function or state variable:
- usdcDividendRewardsFee.add(marketingFee).add(wbnbDividendRewardsFee).add(liquidityFee).add(buybackFee)
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.
