CVE-2026-104107 Details
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.
A path traversal vulnerability has been identified in FileRise version 3.22.0. The issue arises in the '/api/file/saveFile.php' operation, where the application accepts dot and dot-dot segments in the folder input. This unvalidated input can be exploited by authenticated non-administrator users with inherited edit permissions, allowing them to create files outside of the authorized directory and, in the case of WebDAV, beyond the designated WebDAV root. The vulnerability stems from improper handling of folder names, which can be manipulated to traverse the file system or WebDAV paths, bypassing access controls and potentially leading to unauthorized file creation in sensitive areas.
Users can upgrade to FileRise version 3.23.0, which addresses the vulnerability by rejecting dot segments in folder paths, enforcing proper path validation before authorization checks, and ensuring that WebDAV operations remain within the configured source root.
