How to Fix GHSA-8r4g-cg4m-x23c

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

node-static fixed: Latest secure release 
npm install node-static@Latest secure release
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 node-static

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-8r4g-cg4m-x23c, inspect your project dependencies using npm:

npm ls node-static

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

Note: The npm ls node-static 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Node static, 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

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.
