CVE-2026-72593Network attack vectorHinoki check available

Unauthenticated filesystem access via empty default password

Published Aug 10, 2026 · Updated Aug 10, 2026

Missing authentication in Dulldusk phpFileManager 1.8.0 and earlier allows remote attackers to control files through its web interface. The single-file script initializes auth_pass to an empty string and routes requests directly to file-manager actions whenever that value is empty, bypassing the login form. Exposure requires deployment at a network-reachable URL without configuring a password; the PHP process can read, write, delete, upload, and execute files within its operating-system permissions.
