Submission Details
Severity:
Incorrect event is triggered in BidBeastsNFTMarket::placeBid
Description\
AuctionSettled event is triggered every time in function `BidBeastsNFTMarket::placeBid. That is not correct because actually the auction is not settled yet. This can affect external integrations that rely on events.
function placeBid(uint256 tokenId) external payable isListed(tokenId) {
...
if (listing.buyNowPrice > 0 && msg.value >= listing.buyNowPrice) {
...
return;
}
require(msg.sender != previousBidder, "Already highest bidder");
@> emit AuctionSettled(tokenId, msg.sender, listing.seller, msg.value);
...
}
Risk
Likelihood: High
Event is triggered on every bid.
Impact: Low
It affects only events.
Recommended Mitigation
Remove the event triggering from the function:
- emit AuctionSettled(tokenId, msg.sender, listing.seller, msg.value);
