CVE-2026-41583

ZEBRA: Consensus Divergence in Transparent Sighash Hash-Type Handling (CVE-2026-41583). Zebra, a Rust-based Zcash node, failed after a refactor to validate sighash hash-type limits for V5 (NU5) and V4 transactions. This could allow Zebra to accept/mined blocks that zcashd would reject, causing a ...
