What is CVE-2026-62664?

FileRise, a self-hosted web-based file manager, has a directory traversal vulnerability that allows authenticated low-privileged users to create directories outside the intended upload directory. This issue arises from improper validation of folder names, specifically failing to reject dot-dot path segments before executing folder creation operations. As a result, a user with valid permissions can exploit this flaw using an authorized CSRF token to send POST requests to create folders in unauthorized locations. The vulnerability is mitigated in version 3.19.0.

Affected Version(s)

FileRise < 3.19.0
