Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.19, split-royalty fields decoded in core/kapp/builtInFunctions/utils.go can contain values greater than core.HundredPercent, and core/kapp/kda/create.go and core/kapp/kda/trigger.go sum those values in uint32 accumulators. Crafted values such as two 0x80000000 entries wrap the validation sum to zero and pass CheckValid100Params. Royalty payout paths in core/kapp/accounts/accounts.go, core/kapp/market/market.go, and core/kapp/ito/ito.go then credit each oversized split amount and silently discard a negative remainder, allowing ordinary asset transfers, marketplace purchases, or ITO purchases to create unbacked KLV or other assets. This issue is fixed in version 1.7.19.
