firestore-litenpm
Advisory published Updated
firestore-lite is a confirmed malicious npm package (MAL-2026-15534) that typosquats a legitimate package to trick installs (malicious version 45.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in firestore-lite (npm)
What this malware does
package.json declares a single dependency whose value is a bare HTTP URL (https://repo.securityctrl.com/firestore-lite) rather than a registry version range. On npm install, npm fetches and installs whatever tarball that URL returns, running any lifecycle scripts contained in it, with no version pin and no integrity check. The dependency key is the package's own name, a dependency-confusion shape, and the shipped index.js is an inert stub — the manifest line is the entire published payload. The package name mimics the legitimate Firebase 'firestore-lite' module, and the version 45.0.0 is implausibly high for that name, consistent with an attempt to win version resolution against an internal package.
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.

Detection & response playbook
TyposquatFind it
Search your lockfiles and build artifacts for firestore-lite (version 45.0.0).
If you installed it — respond
firestore-lite is a typosquat — you almost certainly intended a legitimately-named package. Remove firestore-lite, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If firestore-lite was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks firestore-lite-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
