UMBP [UmbrellaProtocol] Token

UmbrellaProtocol.swapBNBForUSDT(uint256) (#1947-1962) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: tokenAmount}(0,path,address(this),block.timestamp) (#1956-1961)
UmbrellaProtocol.addLiquidity(uint256,uint256) (#1998-2011) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (#2003-2010)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Contract ownership is not renounced (belongs to a wallet)

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.

USDTDividendTracker.getAccount(address) (#1292-1336) uses timestamp for comparisons
Dangerous comparisons:
- nextClaimTime > block.timestamp (#1333-1335)
USDTDividendTracker.canAutoClaim(uint256) (#1357-1363) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (#1358)
- block.timestamp.sub(lastClaimTime) >= claimWait (#1362)
Avoid relying on block.timestamp.
