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

Quick assessment

Affected
nimiq core-rs-albatross
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Nimiq 是一个基于 Albatross 共识算法的 Nimiq 权益证明（Proof-of-Stake）协议的 Rust 实现。在 1.6.0 版本之前，恶意的状态同步对等节点可以通过发送一个精心构造的 TrieChunk 证明来使正在同步的节点崩溃，该证明中包含两个具有相同键值的 TrieProofNode。具体地， 调用了位于 中的 。其中， 接受相同的键，而 在键的长度处被调用，返回 ，并且该结果被无条件地解包（unwrap）。不可信的 数据在密码学证明验证之前就会到达 、 以及 ，因此攻击者无需提供有效

Vulnerability Title
Nimiq: Panic in TrieProof::verify via child_index unwrap on equal-length keys
Source: CVE Program / CVE List V5
Vulnerability Description
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 calls TrieProofNode::child_index in primitives/src/trie/trie_proof_node.rs, where is_prefix_of accepts equal keys and KeyNibbles::get is called at the key length, returns None, and is unconditionally unwrapped. Untrusted ResponseChunk data reaches commit_chunks, put_chunk, and proof.verify before cryptographic proof validation, so the attacker does not need a valid proof. Exploitation requires the attacker to be selected as the victim's sync peer during state sync, and the resulting panic is transient because the node restarts and resynchronizes. This issue is fixed in version 1.6.0.
