CVE-2026-47249

Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.18, the P2P resolver request handling logic is vulnerable to hash-array amplification. A connected peer can send a compressed RequestDataTypeHashArrayType direct request that is only 442 bytes on the wire but expan...

CVE-2026-47249

CVE-2026-47249 affects Klever-Go KVM (Go implementation of Klever) prior to v1.7.18. The issue is in P2P resolver request handling where a compressed RequestDataType_HashArrayType direct request (wire size ~442 bytes) can expand into about 200,000 decoded hash entries inside the resolver path. Th...

Klever-Go KVM: Hash-array amplification in P2P resolver request handling

Summary A connected peer can send a compressed RequestDataTypeHashArrayType direct request that is only 442 bytes on the wire but expands into 200000 decoded hash entries inside the resolver path. On klever-go v1.7.17, this allows remote memory and CPU amplification against nodes that accept P2P...
