Published Jun 9, 2026 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed
Description
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.
