Two split entries whose percentages sum to\njust over `2^32` **wrap around** below `10000` and pass validation, while each stored value\nremains astronomically large (e.g. `0x80000000 = 2,147,483,648` ≈ 21,474,836%).\n\nAt royalty payout, each split recipient is credited `pool × hugePct / 10000` — far more than\nthe royalty pool — and the resulting negative remainder is silently discarded\n(`if royaltiesToPay <= 0 { return Ok }`). Because **fixed** royalties (and marketplace/ITO\nroyalties) are denominated in **KLV**, an attacker mints **KLV (the native token)** out of thin\nair, on demand, by transferring or selling their own throwaway asset.\n\nThis is independent of, and not mitigated by, the existing `FixMarketBuyOverflow` guard.\n\n\n## Affected component\n\n- Repository: `klever-io/klever-go` (node).\n- Validation: `core/process/kda/assetHelper.go`, `core/kapp/kda/create.go`,\n  `core/kapp/kda/trigger.go`, `core/kapp/builtInFunctions/utils.go`.\n- Payout","public_affected_ranges":["< 1.7.19"]}],"null_published_at":"2026-11-02T10:00:37.201Z","source_updated_at":"2026-08-28T16:25:49.000Z","source_disclosed_at":"2026-08-28T16:25:48.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-02T09:56:23.004Z"}],"next_cursor":null,"snapshot_revision":"42594"}
