How to Fix CVE-2017-0928

To remediate this vulnerability, upgrade all affected Html janitor 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-janitor fixed: Latest secure release 
npm install html-janitor@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-janitor

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2017-0928, inspect your project dependencies using npm:

npm ls html-janitor

Analyze the terminal output to locate any version of Html janitor 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-janitor 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-642: External Control of Critical State Data, where the product stores security-critical state information about its users, or the product itself, in a location that is accessible to unauthorized actors. In Html janitor, 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-janitor` are vulnerable to cross-site scripting (XSS). Arbitrary HTML can pass the sanitization process, which can be unexpected and dangerous (XSS) in case user-controlled input is passed to the clean function." ## Recommendation Upgrade to version 2.0.4 or later.
