CVE-2026-40093

nimiq-blockchain provides persistent block storage for Nimiq's Rust implementation. In 1.3.0 and earlier, block timestamp validation enforces that timestamp = parent.timestamp for non-skip blocks and timestamp == parent.timestamp + MINPRODUCERTIMEOUT for skip blocks, but there is no visible upper...

GHSA-49XC-52MP-CC9J nimiq-blockchain is missing a wall-clock upper bound on block timestamps

Impact Block timestamp validation enforces that timestamp = parent.timestamp for non-skip blocks and timestamp == parent.timestamp + MINPRODUCERTIMEOUT for skip blocks, but there is no visible upper bound check against the wall clock. A malicious block-producing validator can set block timestamps...
