CVE-2026-54542

Nimiq is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Prior to 1.6.0, a malicious state-sync peer can crash a syncing node by sending a crafted TrieChunk whose proof contains a TrieNodeChild suffix that is individually valid but exceeds th...

CVE-2026-54542

Nimiq core-rs-albatross (the nimiq-primitives crate) versions ≤ 1.5.1 are affected by an out-of-bounds panic in KeyNibbles::Add (primitives/src/key_nibbles.rs). The method indexes a 63-byte backing array with the combined length of a parent key and a child suffix without bounds-checking the total...

CVE-2026-54542 Nimiq: Out-of-bounds panic in KeyNibbles::Add from oversized child suffix in a deserialized proof

Nimiq is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Prior to 1.6.0, a malicious state-sync peer can crash a syncing node by sending a crafted TrieChunk whose proof contains a TrieNodeChild suffix that is individually valid but exceeds th...

CVE-2026-54542: Out-of-bounds Read

Nimiq is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Prior to 1.6.0, a malicious state-sync peer can crash a syncing node by sending a crafted TrieChunk whose proof contains a TrieNodeChild suffix that is individually valid but exceeds th...

CVE-2026-54541: Uncaught Exception

Nimiq is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Prior to 1.6.0, a malicious state-sync peer can crash a syncing node by sending a crafted TrieChunk proof containing two TrieProofNode values with identical keys. TrieProof::verify call...

GHSA-46WQ-28CX-MHW4 nimiq-primitives: Panic in TrieProof::verify via child_index unwrap on equal-length keys

Impact A malicious peer acting as a state-sync source can crash a syncing node by sending a crafted TrieChunk whose proof contains two TrieProofNodes with identical keys. TrieProof::verify calls TrieProofNode::childindex primitives/src/trie/trieproofnode.rs:94, which unconditionally unwraps...
