Hickory DNS：DNS签名验证缺少对所属域的核对

11月8日公开的漏洞记录CVE-2026-123605涉及Hickory DNS。验证程序会查找签名者名称对应的密钥，却漏掉关键一步，查证这个名称是否属于正在验证的记录集所在的域。这使掌握一个已签名域的参与者有机会为另一个无关域的记录背书，并使依赖该程序的解析器接受错误结果。公告分别列出了网络库和协议库的范围。版本清单标出的受影响范围包括0.1至0.25.0-alpha.3（含）。

这条记录给出的CVSS 3.1基础评分为8.8分，分级为高危。按照评分列出的条件，利用者可通过网络接触相关功能，需要已有低权限账户或相当的访问权，并且无需另一名用户进行额外交互。数据保密性、内容完整性和服务可用性三项的影响等级分别为高、高、高。评分把利用复杂度列为较低，所反映的是触发这一缺陷需要满足的技术条件。
