Severity:
During liquidation when NFTs are are transferred to the stability pool, there is no way to withdraw them later.
Bug description
When liquidation is finalized, the NFTs used as collateral by borrower are transferred to the stability pool.
// Transfer NFTs to Stability Pool
for (uint256 i = 0; i < user.nftTokenIds.length; i++) {
uint256 tokenId = user.nftTokenIds[i];
user.depositedNFTs[tokenId] = false;
raacNFT.transferFrom(address(this), stabilityPool, tokenId);
}
However, after NFTs are transferred to stability pool, there's no way to withdraw them and they will be stuck in the contract.
Impact
NFTs transferred to stability pool during liquidation are lost.
Recommended Mitigation
Add a way to withdraw NFTs from the stability pool.
