In the world of software development, we often take for granted the security and reliability of the tools and platforms we rely on daily. We assume that the packages we download and the registries we use are safe and trustworthy. However, at Lupin & Holmes we've recently discovered a Cache Poisoning Attack on the npm registry, one of the largest package registry for JavaScript, potentially exposing the fragility of our Software Supply Chains and the potential for widespread disruption.

The npm registry is a critical component of the JavaScript ecosystem, serving as a central repository for over 2.1 million packages and relied upon by more than 17 million developers worldwide. It has become an indispensable resource, enabling them to easily share, reuse, and manage dependencies in their projects. With millions of downloads per day, the npm registry is the backbone of countless applications and websites.

In this article, we will discuss the details of the cache poisoning attack on npm and explore its potential impact on the broader software ecosystem. By disclosing publicly this vulnerability, we aim to show the importance of security and availability in our Software Supply Chains.
