CVE-2026-46403

Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.17, KVM exposes ExecuteReadOnlyWithTypedArguments as a read-only execution mechanism. The hook saves the previous read-only state, sets runtime.SetReadOnlytrue, executes the destination context, and then restores t...

GHSA-JC6W-WMFC-FH33 Klever-Go KVM read-only execution can commit contract delete and upgrade side effects

Publisher note Fixed in v1.7.17. Operators running v1.7.17 should upgrade. Contract delete and upgrade host-core paths now reject execution when runtime.ReadOnly is true. The invariant is regression-tested for delete, upgrade, storage writes, value transfers, and any VM output field that can late...
