CVE-2023-46298

CVE-2023-46298 is a low-severity security vulnerability in next (npm), affecting versions >= 0.9.9, < 13.4.20-canary.13. It is fixed in 13.4.20-canary.13.

Summary

Next.js before 13.4.20-canary.13 lacks a cache-control header and thus empty prefetch responses may sometimes be cached by a CDN, causing a denial of service to all users requesting the same URL via that CDN. Cloudflare considers these requests cacheable assets.

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

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. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

  2. Which versions of next are affected by CVE-2023-46298? next (npm) versions >= 0.9.9, < 13.4.20-canary.13 is affected.
  3. Is there a fix for CVE-2023-46298? Yes. CVE-2023-46298 is fixed in 13.4.20-canary.13. Upgrade to this version or later.
  4. Is CVE-2023-46298 exploitable, and should I be worried? Whether CVE-2023-46298 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.

  5. What actually determines whether CVE-2023-46298 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.
  6. How do I fix CVE-2023-46298? Upgrade next to 13.4.20-canary.13 or later.
