How to Fix GHSA-vcvr-r3jv-pc5j

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

next fixed: 16.3.6 
npm install next@16.3.6
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 next

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-vcvr-r3jv-pc5j, inspect your project dependencies using npm:

npm ls next

Analyze the terminal output to locate any version of Next in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 16.3.6), your application is affected.

Note: The npm ls next 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-1395: Dependency on Vulnerable Third-Party Component, where the product has a dependency on a third-party component that contains one or more known vulnerabilities. In Next, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Impact The Node.js `ImageResponse` implementation from `next/og` is affected by an upstream vulnerability. This can lead to remote code execution. Affected applications pass attacker-controlled values into SVG content, attributes, or styles during image generation: ```tsx import { ImageResponse } from 'next/og' export async function GET(request: Request) { const value = new URL(request.url).searchParams.get('value') ?? '' return new ImageResponse( <svg width="1200" height="630"> <title>{value}</title> </svg> ) } ``` Applications using the Edge `ImageResponse` implementation, or applications that do not pass attacker-controlled values into SVG content, attributes, or styles, are not affected. ## Workaround If upgrading is not immediately possible, do not pass attacker-controlled values into SVG content, attributes, or styles rendered by the Node.js `ImageResponse` implementation from `next/og`.
