devalue：序列化稀疏数组可能耗尽服务资源

11月8日公开的漏洞记录CVE-2026-123569涉及devalue。这个JavaScript软件包可将内存中的数据转换成便于传递的表示形式。受影响的两种序列化操作遇到很长但只填入少量元素的数组时，可能耗费过多处理器时间与内存。触发还要求这类数组先在服务端生成，常见的网络传输格式本身不直接提供这种输入。版本清单标出的受影响范围包括5.6.3之前的版本。记录另将5.6.3列为不受影响的版本。

这条记录给出的CVSS 3.1基础评分为7.5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，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。
