Auth bypass in Error311 Filerise

CVE-2026-57492

FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.16.0, FileRise treats an empty or missing users.txt file as a fresh installation even after setup previously completed. If storage loss, truncation, or another failure empties the user store, an unauthenticated remote caller can detect that setup mode reopened and create the next initial administrator account through the setup flow. The application lacked a durable setup-complete marker independent of the mutable user store. This issue is fixed in version 3.16.0.
