LUNADAO Token

LUNADAO.swapBNBForLUNA(uint256) (#1952-1969) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: tokenAmount}(0,path,address(this),block.timestamp) (#1963-1968)
LUNADAO.addLiquidity(uint256,uint256) (#2005-2018) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (#2010-2017)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

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.

LUNADAO.claim() (#1804-1806) ignores return value by dividendTracker.processAccount(msg.sender,false) (#1805)
