MTVG [Metaverse Box Game] Token

MTVG.addLiquidity(uint256,uint256) (#818-828) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#820-827)
MTVG.sendValueTo(address,uint256) (#892-896) sends eth to arbitrary user
Dangerous calls:
- (success) = to.call{value: value}() (#894)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Contract ownership is not renounced (belongs to a wallet)

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.
