CVE-2026-46403

Summary (verified): Klever-Go KVM read-only execution can leak state changes via contract delete/upgrade side effects when invoked through ExecuteReadOnlyWithTypedArguments. The root cause is applying read-only as runtime state while not enforcing it in state-changing host-core paths, allowing a ...
