Descriptions

Deno is a JavaScript, TypeScript, and WebAssembly runtime. Starting in version 1.8.0 and prior to version 1.40.4, Deno improperly checks that an import specifier's hostname is equal to or a child of a token's hostname, which can cause tokens to be sent to servers they shouldn't be sent to. An auth token intended for `example[.]com` may be sent to `notexample[.]com`. Anyone who uses DENO_AUTH_TOKENS and imports potentially untrusted code is affected. Version 1.40.0 contains a patch for this issue

Deno es un tiempo de ejecución de JavaScript, TypeScript y WebAssembly. A partir de la versión 1.8.0 y antes de la versión 1.40.4, Deno verifica incorrectamente que el nombre de host de un especificador de importación sea igual o hijo del nombre de host de un token, lo que puede causar que los tokens se envíen a servidores a los que no deberían enviarse. Un token de autenticación destinado a `example[.]com` puede enviarse a `notexample[.]com`. Cualquiera que utilice DENO_AUTH_TOKENS e importe código potencialmente no confiable se verá afectado. La versión 1.40.0 contiene un parche para este problema
