CVE-2025-52662 · Severity: medium · CVSS 6.9 · Published 2025-11-07

Nuxt DevTools is a browser extension used by developers to debug Nuxt.js applications. A cross-site scripting (XSS) vulnerability in the authentication component could allow an attacker to extract authentication tokens and hijack developer sessions, potentially compromising sensitive project data or credentials.

Technologies: [@nuxt/devtools (npm)](https://junglewise.ai/threats/technologies/nuxt-devtools), [Nuxt DevTools](https://junglewise.ai/threats/technologies/devtools). Vendors: [npm](https://junglewise.ai/threats/vendors/npm), [Nuxt](https://junglewise.ai/threats/vendors/nuxt).

  ```sh
  npm install @nuxt/devtools@2.6.4
  ```


## Technical details

A reflected XSS vulnerability exists in Nuxt DevTools' authentication page (CWE-79) due to unsafe DOM manipulation using `innerHTML` instead of `textContent`. The vulnerability affects all versions prior to 2.6.4. The attack requires user interaction (clicking a malicious link) and a specific configuration, but is network-accessible. A successful exploit allows extraction of Nuxt auth tokens and potential session hijacking. The fix replaces `innerHTML` with `textContent` in the auth component to prevent script injection.
