CVE-2022-23646

Next.js is a React framework. Starting with version 10.0.0 and prior to version 12.1.0, Next.js is vulnerable to User Interface (UI) Misrepresentation of Critical Information. In order to be affected, the next.config.js file must have an images.domains array assigned and the image host assigned in images.domains must allow user-provided SVG. If the next.config.js file has images.loader assigned to something other than default, the instance is not affected. Version 12.1.0 contains a patch for this issue. As a workaround, change next.config.js to use a different loader configuration other than the default.

Workarounds

Change next.config.js to use a different loader configuration other than the default, for example:

module.exports = {
  images: {
    loader: 'imgix',
    path: 'https://example.com/myaccount/',
  },
}

Or if you want to use the loader prop on the component, you can use custom:

module.exports = {
  images: {
    loader: 'custom',
  },
}

• Affected: All of the following must be true to be affected
  • Next.js between version 10.0.0 and 12.0.10
  • The next.config.js file has images.domains array assigned
  • The image host assigned in images.domains allows user-provided SVG
• Not affected: The next.config.js file has images.loader assigned to something other than default

CVE-2022-23646 has a CVSS score of 5.9 (Medium). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (12.1.0); upgrading removes the vulnerable code path.

1. What is CVE-2022-23646? CVE-2022-23646 is a medium-severity security vulnerability in next (npm), affecting versions >= 10.0.0, < 12.1.0. It is fixed in 12.1.0.
2. How severe is CVE-2022-23646? CVE-2022-23646 has a CVSS score of 5.9 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of next are affected by CVE-2022-23646? next (npm) versions >= 10.0.0, < 12.1.0 is affected.
4. Is there a fix for CVE-2022-23646? Yes. CVE-2022-23646 is fixed in 12.1.0. Upgrade to this version or later.
5. Is CVE-2022-23646 exploitable, and should I be worried? Whether CVE-2022-23646 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2022-23646 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2022-23646? Upgrade next to 12.1.0 or later.
