FreedomBox：账户密钥文件处理不当可能越过文件权限

11月7日公开的漏洞记录CVE-2026-123962涉及FreedomBox。普通账户对获准登录密钥的文件位置拥有一定控制权。如果该位置指向另一文件，特定版本可能跟随链接执行读写，使实际访问超出账户原有权限。公告将影响范围定位到26.15之前，并说明该系统的软件通过Debian软件库分发。版本清单标出的受影响范围包括26.15之前的版本。

这条记录给出的CVSS 3.1基础评分为8.4分，分级为高危。按照评分列出的条件，利用者需要具备本地访问条件，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。
