Summary
Denial of Service in node-static
All versions of node-static are vulnerable to a Denial of Service. The package fails to catch an exception when user input includes null bytes. This allows attackers to access http://host/%00 and crash the server.
Impact
Crafted input forces the application to consume excessive CPU, memory, or other resources, degrading or denying service. Typical impact: denial of service.
Affected versions
Security releases
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.

In the interim: Apply input size limits and request rate limiting. Reject input that exceeds reasonable bounds before processing begins.

Frequently Asked Questions
- What is GHSA-8R4G-CG4M-X23C? GHSA-8R4G-CG4M-X23C is a medium-severity uncontrolled resource consumption vulnerability in node-static (npm), affecting versions <= 0.7.11. No fixed version is listed yet. Crafted input forces the application to consume excessive CPU, memory, or other resources, degrading or denying service.
- Which versions of node-static are affected by GHSA-8R4G-CG4M-X23C? node-static (npm) versions <= 0.7.11 is affected.
- Is there a fix for GHSA-8R4G-CG4M-X23C? No fixed version is listed for GHSA-8R4G-CG4M-X23C yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is GHSA-8R4G-CG4M-X23C exploitable, and should I be worried? Whether GHSA-8R4G-CG4M-X23C 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.

- What actually determines whether GHSA-8R4G-CG4M-X23C 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.
- How do I fix GHSA-8R4G-CG4M-X23C? No fixed version is listed yet. In the interim: Apply input size limits and request rate limiting. Reject input that exceeds reasonable bounds before processing begins.
