CVE-2026-46541: Nimiq Core-RS-Albatross

High severity, CVSS 7.5. EPSS: 0.6% chance of exploitation in the next 30 days.

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.

Affected products

• Nimiq Core-RS-Albatross: before 1.4.0 (fixed in 1.4.0)
