CVE-2026-62683— FileBrowser 授权问题漏洞

File Browser: Trailing-slash delete leaves a stale public share behind

File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to 2.63.17, File Browser can leave a public directory share behind when the shared directory is deleted through a path with a trailing slash because the share cleanup path calls DeleteWithPathPrefix(file.Path, userID) and the Bolt backend performs the database prefix query with the unnormalized path before trimming the slash for boundary checks, so deleting /a/ does not delete the stored /a share and the stale public share exposes future content if the same path is recreated. This issue is fixed in version 2.63.17.

授权机制不正确

FileBrowser 授权问题漏洞

FileBrowser是filebrowser团队开源的一个文件管理界面，在指定的目录，它可以用来上传、删除、预览和编辑文件。 FileBrowser 2.63.17之前版本存在授权问题漏洞，该漏洞源于目录共享清理路径调用DeleteWithPathPrefix(file.Path, userID)时Bolt后端在边界检查前对未规范化路径执行数据库前缀查询，导致通过尾部斜杠路径删除共享目录时未清除已存储的共享，如果相同路径被重新创建，过时的公共共享会暴露未来内容。
