CVE-2026-54541

Nimiq core-rs-albatross (≤ 1.5.1) contains a denial-of-service vulnerability in the TrieProof verification path used during state sync. A malicious sync peer can send a crafted TrieChunk containing two TrieProofNode values with identical keys, triggering an unconditional unwrap() on KeyNibbles::g...

CVE-2026-54541 Nimiq: Panic in TrieProof::verify via child_index unwrap on equal-length keys

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...

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...
