CVE-2026-46545 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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). EPSS estimates a 0.34% chance of exploitation in the next 30 days.
