CVE-2026-11841

An attacker can read and write sensitive files on the device through the AppEngine Fileaccess over HTTP because the system does not enforce authentication. The exposed directories include device parameter files and the custom application directory, allowing attackers to change settings, passwords, or run arbitrary Lua code. This flaw can lead to serious compromise of the device.
