Descriptions

Deno is a JavaScript, TypeScript, and WebAssembly runtime with secure defaults. Insufficient validation of parameters in `Deno.makeTemp*` APIs would allow for creation of files outside of the allowed directories. This may allow the user to overwrite important files on the system that may affect other systems. A user may provide a prefix or suffix to a `Deno.makeTemp*` API containing path traversal characters. This is fixed in Deno 1.41.1.

Deno es un tiempo de ejecución de JavaScript, TypeScript y WebAssembly con valores predeterminados seguros. Una validación insuficiente de los parámetros en las API `Deno.makeTemp*` permitiría la creación de archivos fuera de los directorios permitidos. Esto puede permitir al usuario sobrescribir archivos importantes en el sistema que pueden afectar a otros sistemas. Un usuario puede proporcionar un prefijo o sufijo a una API `Deno.makeTemp*` que contenga caracteres de path traversal. Esto se solucionó en Deno 1.41.1.
