Background
tailwindcss-keyframe-kit is a Tailwind CSS plugin designed to facilitate the integration of animations into web applications. It allows developers to easily implement keyframe animations using Tailwind's utility-first approach. However, this package has been compromised, exposing users to potential security risks due to malicious code embedded in a private dependency.
Vulnerability Detail
