CVE-2026-52878 Klever-Go: Unauthenticated nil-pointer DoS in P2P transaction validation can halt the chain

Klever-Go is the Go implementation of the Klever blockchain protocol. Versions 1.7.14 through 1.7.17 are vulnerable to a nil-pointer panic triggered by a protobuf Transaction whose embedded RawData sub-message is omitted. This omission causes RawData to decode to nil. Every transaction gossiped o...

Name of the Vulnerable Software and Affected Versions Klever-Go versions 1.7.14 through 1.7.17 Description A nil-pointer panic can be triggered by a protobuf Transaction where the embedded RawData sub-message is omitted, causing RawData to decode to nil. During the decoding and validation of...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to unknown fields that aren't checked. An attacker can disrupt consensus and cause all block proposals to be rejected by submitting specially crafted vote extensions with...

Babylon's malformed vote extensions are not rejected

Summary Adversarial validators can send large vote extensions by using non-existing protobuf tags. This will result in the rejection of the subsequent block proposal. Eventually, all block proposals will be rejected by all validators. Impact A small group of adversarial validators can cause a cha...
