How to Fix GHSA-m489-xr35-fjxr

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

millisecond fixed: 0.1.2 
npm install millisecond@0.1.2
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 millisecond

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-m489-xr35-fjxr, inspect your project dependencies using npm:

npm ls millisecond

Analyze the terminal output to locate any version of Millisecond in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.1.2), your application is affected.

Note: The npm ls millisecond 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 Millisecond, 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

Versions of `millisecond` prior to 0.1.2 are affected by a regular expression denial of service vulnerability when extremely long version strings are parsed. ## Proof of concept ``` var ms = require('millisecond'); var genstr = function (len, chr) { var result = ""; for (i=0; i<=len; i++) { result = result + chr; } return result; } ms(genstr(process.argv[2], "5") + " minutea"); ``` ## Recommendation Update to version 0.1.2 or later.
