Cubics.addLiquidity(uint256,uint256) (#313-316) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#315)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Cubics.recover(address,uint256) (#206-209) ignores return value by IERC20(tokenAddress).transfer(owner(),tokenAmount) (#208)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Contract ownership is not renounced (belongs to a wallet)

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Combination 2: Unchecked transfer + 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.

Cubics._transfer(address,address,uint256) (#280-296) contains a tautology or contradiction:
- require(bool,string)(amount >= 0,Transfer amount must be greater or equal zero) (#283)
Fix the incorrect comparison by changing the value type or the comparison.

Cubics.setRouterAndPair(address,address)._uniswapV2Pair (#254) lacks a zero-check on :
- uniswapV2Pair = _uniswapV2Pair (#256)
Check that the address is not zero.
