Prior to 4.3, an unauthenticated path traversal vulnerability in load_preset() allows reading any .yaml file on the server filesystem. The parsed YAML key-value pairs (including passwords, API keys, connection strings) are returned in the API response. This vulnerability is fixed in 4.3."

Antes de 4.3, una vulnerabilidad de salto de ruta no autenticada en load_preset() permite la lectura de cualquier archivo .yaml en el sistema de archivos del servidor. Los pares clave-valor YAML analizados (incluyendo contraseñas, claves API, cadenas de conexión) se devuelven en la respuesta de la API. Esta vulnerabilidad está corregida en 4.3."
