JSON-java：超长数字可能拖慢JSON解析服务

11月7日公开的漏洞记录CVE-2026-59171涉及JSON-java。Java的JSON解析库在将数字转换成高精度数值前，可能不断累积输入字符而不限制长度。面对外部提供的超长数字，转换需要的处理器时间可能随输入迅速增加。受影响的应用场景包括用相应接口处理不受信任的JSON或XML文档。版本清单标出的受影响范围包括不低于20150729且低于20260719。

这条记录给出的CVSS 3.1基础评分为5.9分，分级为中危。按照评分列出的条件，利用者可通过网络接触相关功能，不以事先取得系统权限为必要条件，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无、无、高。评分把利用复杂度列为较高，所反映的是触发这一缺陷需要满足的技术条件。
