Before 2.5.6, a prior patch aimed to block spawning Windows batch/shell files by returning an error when a spawned path’s extension matched .bat or .cmd. That check performs a case-sensitive comparison against lowercase literals and therefore can be bypassed when the extension uses alternate casing (for example .BAT, .Bat, etc.). This vulnerability is fixed in 2.5.6."},{"lang":"es","value":"Deno es un entorno de ejecución de JavaScript, TypeScript y WebAssembly. Antes de 2.5.6, un parche anterior tenía como objetivo bloquear la ejecución de archivos batch/shell de Windows devolviendo un error cuando la extensión de una ruta ejecutada coincidía con .bat o .cmd. Esa verificación realiza una comparación que distingue entre mayúsculas y minúsculas contra literales en minúsculas y por lo tanto puede ser eludida cuando la extensión utiliza un uso de mayúsculas y minúsculas alternativo (por ejemplo, .BAT, .Bat, etc.).
