Vulnerability Title
nimiq-transaction vulnerable to panic via `HistoryTreeProof` length mismatch
Source: NVD (National Vulnerability Database)
Vulnerability Description
nimiq-transaction provides the transaction primitive to be used in Nimiq's Rust implementation. Prior to version 1.3.0, `HistoryTreeProof::verify` panics on a malformed proof where `history.len() != positions.len()` due to `assert_eq!(history.len(), positions.len())`. The proof object is derived from untrusted p2p responses (`ResponseTransactionsProof.proof`) and is therefore attacker-controlled at the network boundary until validated. A malicious peer could trigger a crash by returning a crafted inclusion proof with a length mismatch. The patch for this vulnerability is included as part of v1.3.0. No known workarounds are available.

Vulnerability Title
Nimiq 安全漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Nimiq是Nimiq开源的一个Albatross协议的Rust实现。 Nimiq 1.3.0之前版本存在安全漏洞，该漏洞源于nimiq-transaction中HistoryTreeProof::verify在格式错误的证明上触发panic，其中history.len() != positions.len()。证明对象源自不受信任的p2p响应，因此在网络边界上受攻击者控制，直到被验证。恶意对等方可以通过返回长度不匹配的特制包含证明来触发崩溃。
