CVE-2025-61668

CVE-2025-61668 is a high-severity null pointer dereference vulnerability in @plone/volto (npm), affecting versions < 16.34.1. It is fixed in 16.34.1, 17.22.2, 18.27.2, 19.0.0-alpha.6.

Summary

Workarounds

Make sure your setup automatically restarts processes that quit with an error. This won't prevent a crash, but it minimises downtime.

Report

The problem was discovered by FHNW, a client of Plone provider kitconcept, who shared it with the Plone Zope Security Team ([email protected]).

Impact

When visiting a specific URL, an anonymous user could cause the NodeJS server part of Volto to quit with an error.

The application dereferences a null pointer, causing a crash. Typical impact: denial of service via crash.

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 @plone/volto are affected by CVE-2025-61668? @plone/volto (npm) versions < 16.34.1 is affected.
  3. Is there a fix for CVE-2025-61668? Yes. CVE-2025-61668 is fixed in 16.34.1, 17.22.2, 18.27.2, 19.0.0-alpha.6. Upgrade to this version or later.
  4. Is CVE-2025-61668 exploitable, and should I be worried? Whether CVE-2025-61668 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-2025-61668 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-2025-61668?
    • Upgrade @plone/volto to 16.34.1 or later
    • Upgrade @plone/volto to 17.22.2 or later
