Background
The mysqljs package is a popular npm package used for connecting to MySQL databases in Node.js applications. It provides a simple and convenient API for executing SQL queries and managing database connections. However, all versions of the package have been found to contain malware that steals environment variables and sends them to attacker-controlled locations.
Vulnerability Detail
The vulnerability in the mysqljs package allows an attacker to hijack environment variables and exfiltrate sensitive information. When the package is installed and executed, it secretly collects environment variables containing credentials, tokens, and other sensitive data. This data is then sent to the attacker's servers, compromising the security and confidentiality of the affected system. The package has been unpublished from the npm registry to prevent further installations.

To fix this vulnerability, follow these steps:
- Delete the
mysqljspackage from your project:npm uninstall mysqljs - Clear your npm cache:
npm cache clean --force - Check if the package is present in any other
package.jsonfiles on your system and remove it if found. - Regenerate any sensitive credentials, tokens, or registry credentials that may have been exposed.
- Review and secure any services that may have been accessed using the compromised environment variables, such as databases or APIs.
