CVE-2026-46541: CWE-754: Improper Check for Unusual or Exceptional Conditions in 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.

Technical Summary
CVE-2026-46541 describes an improper check for unusual or exceptional conditions (CWE-754) in the Nimiq core-rs-albatross implementation of the Albatross consensus algorithm. Before version 1.4.0, the function handle_dht_get() initializes the DhtResults accumulator only when the first DHT record passes verification. If the first record is malicious and fails verification, DhtResults is never created, causing all subsequent valid records to be discarded with "DHT inconsistent state" errors. This results in denial of service by preventing valid DHT data processing. The issue has been addressed in version 1.4.0.
Potential Impact
The vulnerability causes a denial of service (DoS) condition by discarding all valid DHT records if the first record is invalid. This disrupts normal operation of the Nimiq Proof-of-Stake protocol implementation, potentially affecting consensus and network reliability. There is no indication of confidentiality or integrity impact. No known exploits are reported in the wild.
Mitigation Recommendations
A fix is available in Nimiq core-rs-albatross version 1.4.0. Users should upgrade to version 1.4.0 or later to remediate this vulnerability. No other mitigation guidance is provided or required.
