CVE-2025-48888

Deno is a JavaScript, TypeScript, and WebAssembly runtime. Starting in version 1.41.3 and prior to versions 2.1.13, 2.2.13, and 2.3.2, `deno run --allow-read --deny-read main.ts` results in allowed, even though 'deny' should be stronger. The result is the same with all global unary permissions given as `--allow-* --deny-*`. This only affects a nonsensical combination of flags, so there shouldn't be a real impact on the userbase. Users may upgrade to version 2.1.13, 2.2.13, or 2.3.2 to receive a patch.

Summary		(es) Deno es un entorno de ejecución de JavaScript, TypeScript y WebAssembly. A partir de la versión 1.41.3 y anteriores a las versiones 2.1.13, 2.2.13 y 2.3.2, `deno run --allow-read --deny-read main.ts` da como resultado "permitido", aunque `deny' debería ser más seguro. El resultado es el mismo con todos los permisos unarios globales asignados como `--allow-* --deny-*`. Esto solo afecta a una combinación de indicadores sin sentido, por lo que no debería tener un impacto real en la base de usuarios. Los usuarios pueden actualizar a las versiones 2.1.13, 2.2.13 o 2.3.2 para recibir un parche.
