info: name: NestJS DevTools Integration - Remote Code Execution author: nukunga severity: critical description: | Nest is a framework for building scalable Node.js server-side applications. In versions 0.2.0 and below, a critical Remote Code Execution (RCE) vulnerability was discovered in the @nestjs/devtools-integration package. When enabled, the package exposes a local development HTTP server with an API endpoint that uses an unsafe JavaScript sandbox (safe-eval-like implementation). Due to improper sandboxing and missing cross-origin protections, any malicious website visited by a developer can execute arbitrary code on their local machine. The package adds HTTP endpoints to a locally running NestJS development server. One of these endpoints, /inspector/graph/interact, accepts JSON input containing a code field and executes the provided code in a Node.js vm.runInNewContext sandbox. remediation: This is fixed in version 0.2.1. reference: - https://socket.dev/blog/nestjs-rce-vuln - https://github.com/nestjs/nest/security/advisories/GHSA-85cg-cmq5-qjm7 - https://nvd.nist.gov/vuln/detail/CVE-2025-54782 classification: cvss-metrics: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H cvss-score:9.4 cve-id: CVE-2025-54782 cwe-id: CWE-77,CWE-352,CWE-78 metadata: verified:true max-request:1 shodan-query:"devtools.nestjs.com" tags: cve,cve2025,nestjs,rce,sandbox,devtool,unauth
