CVE-2026-46543: CWE-617: Reachable Assertion in nimiq core-rs-albatross
A reachable assertion vulnerability exists in nimiq core-rs-albatross prior to version 1. 5. 0. A remote peer can crash a full node by sending a RequestBatchSet message containing the genesis block's hash, causing a panic due to an assertion failure when processing macro blocks. This issue has been fixed in version 1. 5. 0.
AI Analysis
Technical Summary
Nimiq core-rs-albatross, a Rust implementation of the Nimiq Proof-of-Stake protocol using the Albatross consensus algorithm, contains a reachable assertion vulnerability (CWE-617) in versions before 1.5.0. When a remote peer sends a RequestBatchSet message with the genesis block's hash, the handler calls get_epoch_chunks, which iterates backward through macro blocks using Policy::macro_block_before. Upon reaching the genesis block number, macro_block_before triggers a panic with the message "No macro blocks before genesis block," crashing the full node. This denial-of-service condition has been patched in version 1.5.0.
Potential Impact
An unauthenticated remote attacker can cause a denial-of-service by crashing any full node running an affected version of nimiq core-rs-albatross. The vulnerability does not impact confidentiality or integrity but results in availability loss due to the node crash.
Mitigation Recommendations
This vulnerability is fixed in nimiq core-rs-albatross version 1.5.0. Users should upgrade to version 1.5.0 or later to remediate this issue. Patch status is confirmed by the vendor stating the issue is patched in version 1.5.0.
