      "value": "Deno is a JavaScript, TypeScript, and WebAssembly runtime. From 2.7.0 to 2.7.1,  A command injection vulnerability exists in Deno's node:child_process polyfill (shell: true mode) that bypasses the fix for CVE-2026-27190. The two-stage argument sanitization in transformDenoShellCommand (ext/node/polyfills/internal/child_process.ts) has a priority bug: when an argument contains a $VAR pattern, it is wrapped in double quotes (L1290) instead of single quotes. Double quotes in POSIX sh do not suppress backtick command substitution, allowing injected commands to execute. An attacker who controls arguments passed to spawnSync or spawn with shell: true can execute arbitrary OS commands, bypassing Deno's permission system. This vulnerability is fixed in 2.7.2."

      "value": "Deno es un entorno de ejecución de JavaScript, TypeScript y WebAssembly. Desde 2.7.0 hasta 2.7.1, existe una vulnerabilidad de inyección de comandos en el polyfill node:child_process de Deno (modo shell: true) que elude la corrección para CVE-2026-27190. La sanitización de argumentos en dos etapas en transformDenoShellCommand (ext/node/polyfills/internal/child_process.ts) tiene un error de prioridad: cuando un argumento contiene un patrón $VAR, se envuelve en comillas dobles (L1290) en lugar de comillas simples. Las comillas dobles en POSIX sh no suprimen la sustitución de comandos con comillas invertidas, permitiendo que se ejecuten comandos inyectados. Un atacante que controla los argumentos pasados a spawnSync o spawn con shell: true puede ejecutar comandos arbitrarios del sistema operativo, eludiendo el sistema de permisos de Deno. Esta vulnerabilidad está corregida en 2.7.2."
