Any user can call the auctionEnd function to end the auction.

• Risk: A malicious user could prematurely end the auction or perform a denial of service attack by repeatedly ending the auction, though there is a check to prevent calling it before the auction end time.

• Solution: Implement a check to restrict access to the auctionEnd function, so only the contract owner can call it.
