CVE-2026-35484

text-generation-webui is an open-source web interface for running Large Language Models. 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.

Summary		(es) text-generation-webui es una interfaz web de código abierto para ejecutar Grandes Modelos de Lenguaje. 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.
