How to Fix CVE-2020-15095

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

npm fixed: 6.14.6 
npm install npm@6.14.6
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 npm

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2020-15095, inspect your project dependencies using npm:

npm ls npm

Analyze the terminal output to locate any version of Npm in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 6.14.6), your application is affected.

Note: The npm ls npm 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-532: Insertion of Sensitive Information into Log File, where the product writes sensitive information to a log file. In Npm, 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 the npm CLI prior to 6.14.6 are vulnerable to an information exposure vulnerability through log files. The CLI supports URLs like `<protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>`. The password value is not redacted and is printed to stdout and also to any generated log files.
