Background
The npm CLI is a command-line interface tool used for managing JavaScript packages. It is widely used in the development community to install, publish, and manage dependencies for Node.js projects. The CLI supports various URL formats, including those with passwords. However, versions prior to 6.14.6 have a vulnerability that exposes the password value in log files and printed output.
Vulnerability Detail
This vulnerability, identified as CVE-2020-15095, allows an attacker to obtain sensitive information, specifically passwords, by exploiting the npm CLI's handling of URLs. When a URL with a password is used, the password value is not redacted and is displayed in the command-line output and any generated log files. This can lead to unauthorized access to systems or accounts if the log files are accessible to malicious actors.
