How to Fix GHSA-c53x-wwx2-pg96

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

@berslucas/liljs fixed: 1.0.2 
npm install @berslucas/liljs@1.0.2
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 @berslucas/liljs

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-c53x-wwx2-pg96, inspect your project dependencies using npm:

npm ls @berslucas/liljs

Analyze the terminal output to locate any version of @berslucas/liljs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.2), your application is affected.

Note: The npm ls @berslucas/liljs 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In @berslucas/liljs, 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 `@berslucas/liljs` prior to 1.0.2 are vulnerable to Cross-Site Scripting (XSS). The package uses the unsafe `innerHTML` function without sanitizing input, which may allow attackers to execute arbitrary JavaScript on the victim's browser. ## Recommendation Upgrade to version 1.0.2 or later.
