CERBERUS Token

CerberusToken.addLiquidity(uint256,uint256) (#1311-1324) sends eth to arbitrary user
Dangerous calls:
- cerberusSwapRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,operator(),block.timestamp) (#1316-1323)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

CerberusToken._writeCheckpoint(address,uint32,uint256,uint256) (#1626-1644) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1636)
Don't use strict equality to determine if an account has enough Ether or tokens.

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.

CerberusToken._transfer(address,address,uint256) (#1225-1256) performs a multiplication on the result of a division:
-taxAmount = amount.mul(transferTaxRate).div(10000) (#1242)
-burnAmount = taxAmount.mul(burnRate).div(100) (#1243)
Consider ordering multiplication before division.
