CakeDaoToken._swapToWETHCake() (#861-881) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.swapExactETHForTokens{value: address(this).balance}(0,path,address(this),block.timestamp) (#877)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

CakeDaoToken.setShare(address) (#736-746) uses a dangerous strict equality:

CakeDaoToken.setShare(address) (#736-746) uses a dangerous strict equality:
- IERC20(uniswapV2Pair).balanceOf(shareholder) == 0 (#743)
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.
