How to Fix CVE-2018-16481

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

html-pages fixed: Latest secure release 
npm install html-pages@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 html-pages

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2018-16481, inspect your project dependencies using npm:

npm ls html-pages

Analyze the terminal output to locate any version of Html pages 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 html-pages 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-64: Windows Shortcut Following (.LNK), where the product, when opening a file or directory, does not sufficiently handle when the file is a windows shortcut (.lnk) whose target is outside of the intended control sphere. this could allow an attacker to cause the product to operate on unauthorized files. In Html pages, 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 `html-pages` are vulnerable to Cross-Site Scripting (XSS). The package fails to sanitize folder names, allowing attackers to execute arbitrary JavaScript in the victim's browser through folders with names containing malicious code. ## Recommendation No fix is currently available. Consider using an alternative package until a fix is made available.
