CVE-2026-44498

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 MAXBLOCKSIGOPS, allowing it to accept blocks that zcashd rejects with bad-blk-sigops. A miner who produces such a block...

Nervos CKB BlockTimeTooNew should not be considered as invalid block

Impact Currently, when a node receives a block in future according to its local wall clock, it will mark the block as invalid and ban the peer. If the header's timestamp is more than 15 seconds ahead of our current time. In that case, the header may become valid in the future, and we don't want t...
