CVE-2026-52878: CWE-476: NULL Pointer Dereference in klever-io klever-goCVE-2026-52878
0

Klever-Go versions 1.7.14 through 1.7.17 contain a vulnerability where a nil-pointer dereference occurs due to missing RawData in a protobuf Transaction. This causes a panic that crashes the entire node process when processing transactions on the P2P network. The issue can be triggered by an attacker sending a minimal 3-byte protobuf message without requiring any validator credentials, potentially halting block production and causing a chain halt. The vulnerability is fixed in version 1.7.18.
