An attacker with a mint role can exploit this by passing an extremely large positive value when adding SFT quantity, which overflows a signed 64-bit integer. This bypasses the maximum supply checks and allows minting arbitrary tokens while corrupting the state.\n\n## TL;DR\nInteger overflow in SFT Add Quantity path allows minting beyond MaxSupply limit.\n\n## Technical Details\n\n- **CWE ID**: CWE-190\n- **Attack Vector**: Network (N)\n- **CVSS v4.0**: 8.7\n- **EPSS Score**: 0.00323 (0.32%)\n- **Impact**: High Availability Impact (corrupted state-trie storage, concurrent read/write crashes)\n- **Exploit Status**: POC (Available in public patches and unit tests)\n- **KEV Status**: Not Listed\n\n## Affected Systems\n\n- klever-go\n- **klever-go**: < 1.7.19 (Fixed in: `1.7.19`)\n\n## Mitigation\n\n- Upgrade klever-go to version 1.7.19 or higher.\n- Ensure consensus activation epoch flags for 'fixMarketBuyOverflow' are configured correctly in enableEpochs.yaml.\n\n**Remediation Steps:**\n1. Deploy the v1.7.19 binary to all validators.\n2. Configure enableEpochs.yaml with the target activation epoch for fixMarketBuyOverflow.\n3. Monitor node synchronization and state transition consistency.\n\n## References\n\n- [GitHub Security Advisory](https://github.com/klever-io/klever-go/security/advisories/GHSA-mrpp-v6pg-p54x)\n-
