SantaCoin.buyTokens(uint256,address) (#675-686) sends eth to arbitrary user
Dangerous calls:
- router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,to,block.timestamp) (#680-685)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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.


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.


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.

Additional information: link

SantaCoin.swapThreshold (#464) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 2000
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.
