How to Fix CVE-2017-18355

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

rendertron fixed: 1.1.0 
npm install rendertron@1.1.0
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 rendertron

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2017-18355, inspect your project dependencies using npm:

npm ls rendertron

Analyze the terminal output to locate any version of Rendertron in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.0), your application is affected.

Note: The npm ls rendertron command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
