CVE-2026-46541

nimiq core-rs-albatross

Nimiq is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Prior to version 1.4.0, iIn handle_dht_get(), the DhtResults accumulator is only initialized when the first DHT record passes verification. If the first record fails (from a malicious DHT node), DhtResults is never created, and all subsequent valid records are discarded with "DHT inconsistent state" errors. This issue has been patched in version 1.4.0.
