CVE-2026-2331

critical · 9.8

An attacker may perform unauthenticated read and write operations on sensitive filesystem areas via the AppEngine Fileaccess over HTTP due to improper access restrictions. A critical filesystem directory was unintentionally exposed through the HTTP-based file access feature, allowing access without authentication. This includes device parameter files, enabling an attacker to read and modify application settings, including customer-defined passwords. Additionally, exposure of the custom application directory may allow execution of arbitrary Lua code within the sandboxed AppEngine environment.
