How to Fix CVE-2025-52662

To remediate this vulnerability, upgrade all affected @nuxt/devtools dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@nuxt/devtools fixed: 2.6.4 
npm install @nuxt/devtools@2.6.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @nuxt/devtools

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-52662, inspect your project dependencies using npm:

npm ls @nuxt/devtools

Analyze the terminal output to locate any version of @nuxt/devtools in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.6.4), your application is affected.

Note: The npm ls @nuxt/devtools command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
