      "value": "Tookie is a advanced OSINT information gathering tool. Prior to 4.1fix, modules/modules.py's write_txt, write_csv, write_json, and (commented-but-shipping) scan_file helpers open their output as open(f\"{user}.<ext>\"), where user comes unsanitized from the -u CLI flag or any line of a -U usernames file. A username that contains path-separator sequences (.., /, \\, or an absolute path) causes tookie-osint to write the scan output to an arbitrary path the invoking user has write permission for. This vulnerability is fixed in 4.1fix."

      "value": "Tookie es una herramienta avanzada de recopilación de información OSINT. Antes de 4.1fix, los asistentes write_txt, write_csv, write_json y scan_file (comentado pero distribuido) de modules/modules.py abren su salida como open(f“{user}.[ext]”), donde ’user’ proviene sin sanear del indicador CLI -u o de cualquier línea de un archivo de nombres de usuario -U. Un nombre de usuario que contiene secuencias de separadores de ruta (.., /, \\, o una ruta absoluta) hace que tookie-osint escriba la salida del escaneo a una ruta arbitraria para la que el usuario invocador tiene permiso de escritura. Esta vulnerabilidad está corregida en 4.1fix."
