CVE-2026-40880

The CVE-2026-40880 issue affects Zebra (Zcash node) prior to Zebrad 4.3.1 and zebra-consensus 5.0.2. A logic error in Zebra’s transaction verification cache allowed a malicious miner to exploit height-dependent validity (e.g., an expiry height or upgrade) by submitting a transaction valid at heig...

GHSA-8M29-FPQ5-89JJ Zebra Vulnerable to Consensus Divergence in Transparent Sighash Hash-Type Handling

CVE-2026-41583: Consensus Divergence in Transparent Sighash Hash-Type Handling Summary After a refactoring, Zebra failed to validate a consensus rule that restricted the possible values of sighash hash types for V5 transactions which were enabled in the NU5 network upgrade. Zebra nodes could thus...

CVE-2022-29219

Lodestar is a TypeScript implementation of the Ethereum Consensus specification. Prior to version 0.36.0, there is a possible consensus split given maliciously-crafted AttesterSlashing or ProposerSlashing being included on-chain. Because the developers represent uint64 values as native javascript...

AttesterSlashing number overflow

Impact Possible consensus split given maliciously-crafted AttesterSlashing or ProposerSlashing being included on-chain. Since we represent uint64 values as native javascript numbers, there is an issue when those variables with large greater than 2^53 uint64 values are included on chain. In those...
