In PreMarkets.sol listOffer function changes originOfferInfo only in-memory, but the result is supposed to be stored in storage

Summary

In PreMarkets.sol listOffer function changes originOfferInfo only in-memory, but the result is supposed to be stored in storage

Vulnerability Details

In PreMarkets.sol listOffer function changes originOfferInfo only in-memory, but the result is supposed to be stored in storage - https://github.com/Cyfrin/2024-08-tadle/blob/main/src/core/PreMarkets.sol#L342

if (makerInfo.offerSettleType == OfferSettleType.Turbo) {
address originOffer = makerInfo.originOffer;
OfferInfo memory originOfferInfo = offerInfoMap[originOffer];
if (_collateralRate != originOfferInfo.collateralRate) {
revert InvalidCollateralRate();
}
originOfferInfo.abortOfferStatus = AbortOfferStatus.SubOfferListed;
}

Impact

As a result of this, the originOfferInfo abortOfferStatus will not be set to AbortOfferStatus.SubOfferListed. There is not enough documentation as to what this offer status does but the functions that check for an abortOfferStatus will not function correctly.

Tools Used

Manual review

Recommendations

Change the variable to storage:

OfferInfo memory originOfferInfo = offerInfoMap[originOffer];

Valid high severity, because the `abortOfferStatus` of the offer is not updated and persist through `storage` when listing an offer for turbo mode within the `offerInfoMap` mapping, it allows premature abortion given the `abortOfferStatus` defaults to `Initialized`, allowing the bypass of this [check](https://github.com/Cyfrin/2024-08-tadle/blob/04fd8634701697184a3f3a5558b41c109866e5f8/src/core/PreMarkets.sol#L552-L557) here and allow complete refund of initial collateral + stealing of trade tax which can potentially be gamed for profits using multiple addresses
