Malicious code in fastify-bundler (npm)

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

--- _-= Per source details.

Any consumer that imports fastify-bundler and calls the advertised API executes attacker-supplied JavaScript with full Node privileges; the remote operator can change the payload at any time. The package's declared dependencies (@primno/dpapi for Windows DPAPI credential decryption, better-sqlite3/sqlite3 for Chromium Login Data and Cookies stores, node-machine-id for host fingerprinting, socket.io-client, axios, request) are injected into the require() available to the remote payload, providing a ready-made toolkit for browser-credential theft and C2. The package identity is also deceptive: it is published as 'fastify-bundler' with a description claiming to be a 'high-performance web framework for Node.js', while the shipped README is titled 'Tailwindcss Forms Bundler' and instructs users to `npm install tailwindcss-forms-bundle' — a name/README mismatch targeting three unrelated popular ecosystems to attract installs. ## Source: ghsa-malware (4598c4d755d8e4c070b9218010d931db827742bfae319600afd609c186bcd446) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
