CVE-2026-46545: CWE-248: Uncaught Exception 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 1.5.0, a remote, unauthenticated denial-of-service vulnerability in MerkleRadixTrie::put_chunk allows any state-sync peer to crash any node performing state synchronization (freshly joining nodes and recovering nodes). This issue has been patched in version 1.5.0.
AI Analysis
Technical Summary
CVE-2026-46545 describes a denial-of-service vulnerability in the Nimiq core-rs-albatross Rust implementation of the Albatross consensus algorithm. Specifically, before version 1.5.0, the MerkleRadixTrie::put_chunk function can throw an uncaught exception when processing input from a remote state-sync peer. This allows any unauthenticated state-sync peer to crash nodes that are synchronizing state, including freshly joining or recovering nodes. The vulnerability is fixed in version 1.5.0.
Potential Impact
An unauthenticated remote attacker can cause a denial of service by crashing nodes during state synchronization. This disrupts the availability of nodes joining or recovering on the Nimiq network. There is no impact on confidentiality or integrity reported.
Mitigation Recommendations
Upgrade to Nimiq core-rs-albatross version 1.5.0 or later, where this vulnerability has been patched. No other mitigation or temporary workaround is indicated.
