MAGIC [MAGIC Swap] Token

MagicSwap.buyTokens(uint256,address) (#1287-1298) sends eth to arbitrary user
Dangerous calls:

MagicSwap.depositETH(uint256) (#1380-1389) sends eth to arbitrary user
Dangerous calls:
- IWETH(WBNB).deposit{value: _value}() (#1383)
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.

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.
