      "value": "A path Traversal vulnerability found in FileCodeBox v2.2 and earlier allows arbitrary file writes when application is configured to use local filesystem storage. SystemFileStorage.save_file method in core/storage.py uses filenames from user input without validation to construct save_path and save files. This allows remote attackers to perform arbitrary file writes outside the intended directory by sending crafted POST requests with malicious traversal sequences to /share/file/ upload endpoint, which does not require any authorization."

      "value": "Una vulnerabilidad de salto de ruta encontrada en FileCodeBox v2.2 y versiones anteriores permite escrituras de archivos arbitrarias cuando la aplicación está configurada para usar almacenamiento de sistema de archivos local. El método SystemFileStorage.save_file en core/storage.py utiliza nombres de archivo de la entrada del usuario sin validación para construir la ruta de guardado (save_path) y guardar archivos. Esto permite a atacantes remotos realizar escrituras de archivos arbitrarias fuera del directorio previsto enviando solicitudes POST manipuladas con secuencias de salto maliciosas al endpoint /share/file/ upload, que no requiere ninguna autorización."
