How to Fix CVE-2020-8128

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

jsreport fixed: 2.6.0 
npm install jsreport@2.6.0
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 jsreport

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2020-8128, inspect your project dependencies using npm:

npm ls jsreport

Analyze the terminal output to locate any version of Jsreport in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.6.0), your application is affected.

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