CVE-2026-40094— Nimiq 代码问题漏洞

nimiq-blockchain: network-libp2p untrusted peer can crash address book via empty peer contact addresses

nimiq-blockchain provides persistent block storage for Nimiq's Rust implementation. In versions 1.3.0 and prior, network-libp2p discovery accepts signed PeerContact updates from untrusted peers and stores them in a peer contact book, eventually leading to address book crash. A PeerContact can legally contain an empty addresses list (no intrinsic validation enforces non-empty). Later, PeerContactBook::known_peers builds an address book by taking addresses.first().expect("every peer should have at least one address"). If the attacker has inserted a signed peer contact with addresses=[], any call to get_address_book (RPC/web client) can panic and crash the node/RPC task depending on panic settings. This issue has been fixed in version 1.4.0.

Nimiq 代码问题漏洞

Nimiq是Nimiq开源的一个Albatross协议的Rust实现。 Nimiq 1.3.0及之前版本存在代码问题漏洞，该漏洞源于网络发现接受来自不可信对等节点的签名PeerContact更新并存储，当PeerContact包含空地址列表时，调用get_address_book可能导致恐慌并崩溃节点或RPC任务。
