Report: Update: CVE-2026-44498 - ZEBRA: Block Validator Undercounts Coinbase and P2SH Sigops

CVE ID :CVE-2026-44498 Published : May 8, 2026, 3:09 p.m. | 19 minutes ago Description :ZEBRA is a Zcash node written entirely in Rust. Prior to version 4.4.0, Zebra's block validator undercounts transparent signature operations against the 20000-sigop block limit (MAX_BLOCK_SIGOPS), allowing it to accept blocks that zcashd rejects with bad-blk-sigops. A miner who produces such a block can split the network: Zebra nodes follow the offending chain while zcashd nodes do not. This issue has been patched in version 4.4.0.
