CVE-2026-104107— FileRise: Authenticated path traversal escapes configured storage root through inherited ACLs

Quick assessment

Affected
error311 FileRise
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 FileRise 3.22.0 版本中，/api/file/saveFile.php 接口在接受攻击者控制的文件夹输入时，未经验证便允许包含 "." 和 ".." 路径段，而访问控制列表（ACL）继承机制是在对未规范化路径进行求值之后才进行的。在拥有已认证的非管理员会话、有效的 CSRF 令牌以及对合法父目录具有继承编辑权限的情况下，本地文件系统或 WebDAV 适配器随后会将这些路径段解析为路径导航操作，从而导致攻击者

Vulnerability Title
FileRise: Authenticated path traversal escapes configured storage root through inherited ACLs
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. In FileRise 3.22.0, the /api/file/saveFile.php operation accepts dot and dot-dot segments in its attacker-controlled folder input before ACL inheritance evaluates the uncanonicalized string. With an authenticated non-administrator session, a valid CSRF token, and inherited edit permission on a legitimate ancestor, the local filesystem or WebDAV adapter later resolves those segments as path navigation, permitting attacker-controlled file creation outside the authorized folder and, where backend credentials permit, outside the configured WebDAV root. Local storage also created directories before final containment validation and used a prefix comparison that accepted similarly named sibling roots. This issue is fixed in version 3.23.0.
