DOS of StabilityPool --> NFTLiquidator integration and all other direct Contract -> StabilityPool ETH transfers

ghostbytes

Description

First of all there is no payable receive() or fallback() function implemented in StabilityPool or its parent contracts that can help it to receive ETH. That means everytime there is a direct transfer of ETH to StabilityPool , the transfer will always fail

Now, the NFTLiquidator.buyBackNFT() transfers ETH to the stability pool and due to the description bug this function will always revert and their will possibly be no way to buy back NFT

// https://github.com/Cyfrin/2025-02-raac/blob/main/contracts/core/pools/StabilityPool/NFTLiquidator.sol#L177
function buyBackNFT(uint256 tokenId) external payable {
...
payable(stabilityPool).transfer(price);
...
}
