Docmost 是一款开源的协作式维基和文档软件。在 0.80.1 版本之前，公开的头像和标志图片端点接受攻击者可控的 fileName 路径片段，并在未限制于预期图片目录的情况下将其解析为本地存储路径。未授权的攻击者可以遍历到头像或标志目录之外，读取本地存储中满足路由 UUID 检查条件的对象。该问题已在 0.80.1 版本中得到修复。

Vulnerability Title
Docmost: Public image fileName path traversal leads to unauthorized local file read
Source: CVE Program / CVE List V5
Vulnerability Description
Docmost is open-source collaborative wiki and documentation software. Prior to 0.80.1, the public avatar and logo image endpoint accepts attacker-controlled fileName path segments and resolves them against local storage without confinement to the intended image directory. An unauthenticated attacker can traverse outside the avatar or logo directory and read local storage objects whose final basename satisfies the route's UUID check. This issue is fixed in version 0.80.1.
