CVE-2026-55763

Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.19, processPercentageRoyaltiesTransfer in core/kapp/accounts/accounts.go calls SubFromBalance after the split loop and after the royaltiesToPay royaltiesToPay, so a valid PercentTransferPercentage = 10000 split...

GHSA-V358-WF77-39XV klever-go: Percentage-transfer royalty skips the source debit at exactly-100% splits

Summary In processPercentageRoyaltiesTransfer the royalty pool is collected from the sender by SubFromBalance that is ordered after the split loop and after if royaltiesToPay royaltiesToPay, so a split entry of exactly 100% PercentTransferPercentage = 10000 is a valid config: it drives...

CVE-2026-55763 affects Klever-Go (the Go implementation of the Klever blockchain), prior to version 1.7.19 . In processPercentageRoyaltiesTransfer (core/kapp/accounts/accounts.go), the sender's royalty debit via SubFromBalance is ordered after the split loop and after the royaltiesToPay

CVE-2026-54755

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...

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...

Klever: Integer overflow in split-royalty validation enables unbounded minting of KLV (native token)

Summary The per-entry percentages of a KDA asset's split royalties are validated by summing them into a uint32 accumulator and checking the sum against HundredPercent 10000, with no upper bound on each individual entry. Two split entries whose percentages sum to just over 2^32 wrap around below...

CVE-2026-54755

Klever-Go (the Go implementation of the Klever blockchain) contains a uint32 integer overflow in split-royalty validation. Per-entry royalty percentages are decoded without an upper bound, and the validation sum wraps to zero when two crafted values (e.g., 0x80000000 each) overflow uint32, passin...
