Technical details

The npm package 'ua-parser-js' suffered a supply chain attack where versions 0.7.29, 0.8.0, and 1.0.0 were published containing malicious code (CWE-506). The malware is designed to execute upon installation or runtime, potentially granting attackers full control over the host environment. This allows for the exfiltration of environment variables, secrets, and authentication keys. The vulnerability is triggered via a network-based delivery of the malicious package, though it requires the user to perform an installation or update (User Interaction).
