Upstream information
Description
Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.19, marketplace settlement in core/kapp/market/market.go reads MarketOrderData.ReferralPercentage from the listing while reading asset.Royalties.MarketPercentage live at purchase time. An asset owner can create a valid listing and then use AssetTrigger UpdateRoyalties to make the combined referral and royalty percentages exceed the bid. executeBuyMarket pays referral and royalty amounts unconditionally while computeMarketOwnerAmount silently skips a nonpositive seller remainder, allowing MarketBuy, BuyItNow, or auction Claim settlement to credit more KLV or sale currency than the buyer paid. This can create unbacked currency and corrupt token supply integrity. This issue is fixed in version 1.7.19.SUSE information
