Summary

nimiq-primitives: Panic DoS in trie chunk processing via ROOT-keyed item

Details

Impact

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).

A malicious peer can respond to a RequestChunk with a ResponseChunk::Chunk whose first TrieItem.key is the empty (ROOT) key. The chunk passes sorting, range, and Merkle-proof validation, but when put_raw tries to store a value at the root node, it calls TrieNode::put_value(...).unwrap(), which returns Err(RootCantHaveValue) and panics, aborting the node process. The panic fires on the first malicious chunk the victim commits; no rate limit or authentication gate caps the attack.

Impacted: any node running state sync against untrusted peers — this includes fresh nodes performing initial download and existing nodes recovering from data loss. Honest nodes never construct ROOT-keyed items, so non-syncing operation is unaffected.

Patches

See PR.

Workarounds

There is no safe in-process workaround: any peer serving state-sync data can trigger the crash and the code path is not guarded by a feature flag.

Vulnerability from cvelistv5 – Published: 2026-06-09 23:47 – Updated: 2026-06-10 14:38

Title

nimiq-primitives: Panic DoS in trie chunk processing via ROOT-keyed item

Summary

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.

Severity
