      "value": "Deno is a JavaScript, TypeScript, and WebAssembly runtime. Prior to 2.7.14, Deno's permission system enforces filesystem and execution restrictions by comparing the requested path against the path supplied to --deny-read, --deny-write, --deny-run, or --deny-ffi. On macOS, that comparison was done at the raw-byte level while the APFS filesystem treats different Unicode spellings of the same name as the same file. That means a program could reach a denied path by spelling it differently than the deny rule. This vulnerability is fixed in 2.7.14."

      "value": "Deno es un entorno de ejecución de JavaScript, TypeScript y WebAssembly. Antes de la versión 2.7.14, el sistema de permisos de Deno aplicaba restricciones de sistema de archivos y ejecución comparando la ruta solicitada con la ruta proporcionada a --deny-read, --deny-write, --deny-run o --deny-ffi. En macOS, esa comparación se realizaba a nivel de bytes sin procesar, mientras que el sistema de archivos APFS trata diferentes escrituras Unicode del mismo nombre como el mismo archivo. Eso significa que un programa podría acceder a una ruta denegada escribiéndola de manera diferente a la regla de denegación. Esta vulnerabilidad está corregida en la versión 2.7.14."
