CVE-2020-7789: OS Command Injection in node-notifier. Affects node-notifier versions < 8.0.1. Fixed in 8.0.1. How to fix ↓
Background
node-notifier is an npm package that provides a simple way to display native system notifications on various platforms. It is commonly used in Node.js applications to send notifications to users. However, versions before 8.0.1 are vulnerable to OS command injection. This vulnerability allows an attacker to execute arbitrary commands on Linux machines by exploiting the lack of sanitization of options params when passed as an array.
Vulnerability Detail
The OS command injection vulnerability in node-notifier arises from the insecure handling of user-supplied input. By crafting a malicious array of options, an attacker can inject arbitrary commands that will be executed on the target Linux machine. This can lead to unauthorized access, data leakage, or even complete compromise of the system. The vulnerability has a CVSS score of 5.6, indicating a moderate severity level.
