FKIE_CVE-2026-46541

Vulnerability from fkie_nvd - Published: 2026-06-10 00:16 - Updated: 2026-07-23 09:10
Severity
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
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.
