How to Fix CVE-2022-25940

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

lite-server fixed: Latest secure release 
npm install lite-server@Latest secure release
org.webjars.npm:lite-server fixed: Latest secure release 
<dependency>
    <groupId>org.webjars.npm</groupId>
    <artifactId>lite-server</artifactId>
    <version>Latest secure release</version>
</dependency>
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 lite-server

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-25940, inspect your project dependencies using npm:

npm ls lite-server

Analyze the terminal output to locate any version of Lite server 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 lite-server 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 Lite server, 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.
