      "value": "Deno is a JavaScript, TypeScript, and WebAssembly runtime. Prior to 2.7.10, Deno's node:child_process implementation provided an escapeShellArg() helper used when callers passed shell: true to spawn / spawnSync / exec and friends. On Windows, the helper failed to quote arguments that contained cmd.exe metacharacters and did not neutralize % (which cmd.exe expands even inside double-quoted strings). An attacker who controlled any portion of an argument passed to such a call could inject arbitrary additional commands into the spawned cmd.exe invocation. This vulnerability is fixed in 2.7.10."

      "value": "Deno es un entorno de ejecución de JavaScript, TypeScript y WebAssembly. Antes de la versión 2.7.10, la implementación de node:child_process de Deno proporcionaba una función auxiliar escapeShellArg() utilizada cuando los llamadores pasaban shell: true a spawn / spawnSync / exec y funciones similares. En Windows, la función auxiliar no lograba entrecomillar los argumentos que contenían metacaracteres de cmd.exe y no neutralizaba el % (que cmd.exe expande incluso dentro de cadenas entrecomilladas). Un atacante que controlara cualquier parte de un argumento pasado a dicha llamada podría inyectar comandos adicionales arbitrarios en la invocación de cmd.exe generada. Esta vulnerabilidad está corregida en la versión 2.7.10."
