Malicious package

What to do

Remove vite-plugin-crypto from every project, lockfile and image that pulls it in. Treat any host that installed it as compromised: rotate the credentials, tokens and keys it could read, from a clean machine.

Description

The npm package vite-plugin-crypto versions 1.0.2, 1.0.5, and 1.0.6 contains malicious code that enables arbitrary JavaScript execution on the host running Vite build or dev processes. This occurs because the plugin concatenates user-controllable option fields and passes them to SystemJS's dynamic module loader, allowing an attacker to execute arbitrary code during plugin construction. The package disguises this behavior as a benign cryptographic operation, but it effectively compromises any system where it is installed.

Impact

Any system with vite-plugin-crypto versions 1.0.2, 1.0.5, or 1.0.6 installed or running is fully compromised. Attackers gain arbitrary code execution on the host during Vite build or dev processes, potentially exposing all secrets and keys stored on the machine. Immediate secret and key rotation is required from a clean environment. Removing the package alone does not guarantee removal of all malicious artifacts or backdoors.

Defensive guidance

The package should be removed immediately from all affected systems. All secrets and keys stored on compromised machines must be rotated from a separate, trusted environment. Due to the nature of the compromise, assume full system control by an attacker and perform comprehensive incident response and system rebuilds as necessary. Monitor for any updates or advisories from the package maintainers or security vendors for remediation.

Summary

vite-plugin-crypto@1.0.2, 1.0.5, and 1.0.6 expose a Vite plugin factory that concatenates three option fields (`secret`, `salt`, and `iv`) into a string passed to SystemJS's dynamic import function. This string is treated as a module specifier, causing arbitrary JavaScript code execution on the Vite build or development host each time the plugin config is loaded. The malicious code is disguised as a cryptographic key derivation step, but only `secret` is used in the actual AES-GCM encryption path, while `salt` and `iv` are unused. The promise returned by SystemJS import is discarded, hiding the malicious dynamic loading. This leads to full compromise of any computer running the affected package versions.
