Quick assessment

Affected

Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

FileRise 是一个自托管的基于 Web 的文件管理器，支持多文件上传、编辑和批量操作。在 3.23.0 版本之前，FileRise 的 /api/folder/renameFolder.php 接口存在授权缺陷：它仅对源文件夹验证经过身份认证且持有有效 CSRF 令牌的非管理员、非文件夹作用域用户的权限，但未独立验证目标父文件夹的授权。符合条件的用户若能拥有源文件夹，便可将该文件夹下的整个树形结构移动到其他用户已有的文件夹中，或移至根命名空间；该操作会将移动后所有文件和记录的权限（所有权和 ACL）重新绑定至

Vulnerability Title
FileRise renameFolder omits destination-parent authorization
Source: CVE Program / CVE List V5
Vulnerability Description
FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.23.0, FileRise /api/folder/renameFolder.php authorizes an authenticated, non-folder-scoped, non-administrator with a valid CSRF token against the source folder but does not independently authorize a changed destination parent. A qualifying user who owns a source folder can move that tree beneath another user's existing folder or into the root namespace, and the operation rekeys the moved ownership and ACL records to the new path. The destination must be unused and existing victim files cannot be overwritten. Distinct pre-fix errors reveal whether a specifically guessed destination path exists, but disclose no directory listing or file contents. This issue is fixed in version 3.23.0.
