How to Fix CVE-2018-3748

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

glance fixed: 3.0.8 
npm install glance@3.0.8
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 glance

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2018-3748, inspect your project dependencies using npm:

npm ls glance

Analyze the terminal output to locate any version of Glance in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.8), your application is affected.

Note: The npm ls glance 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 Glance, 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 `glance` before 3.0.8 are vulnerable to Stored Cross-Site Scripting (XSS). This is only exploitable if the attacker is able to control the name of a file that is served by the `glance` package.
