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.

 https://cve.radiocsirt.org/vuln/ghsa-mw3q-r9wh-h2ff GHSA-mw3q-r9wh-h2ff — nimiq-primitives: Panic DoS in trie chunk processing via ROOT-keyed item 2026-10-06T19:31:10.335153+00:00

Affected: crates.io: nimiq-primitives

### 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](https://github.com/nimiq/core-rs-albatross/pull/3762).

### 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.
