Detailsinfo

A vulnerability was found in Qix color-string 2.1.1. It has been declared as critical. This vulnerability affects an unknown functionality. The manipulation with an unknown input leads to a malicious code vulnerability. The CWE definition for the vulnerability is CWE-506. The product contains code that appears to be malicious in nature. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

color-string is a parser and generator for CSS color strings. On 8 September 2025, the npm publishing account for color-string was taken over after a phishing attack. Version 2.1.1 was published, functionally identical to the previous patch version, but with a malware payload added attempting to redirect cryptocurrency transactions to the attacker's own addresses from within browser environments. Local environments, server environments, command line applications, etc. are not affected. If the package was used in a browser context (e.g. a direct inclusion, or via a bundling tool such as Babel, Rollup, Vite, Next.js, etc.) there is a chance the malware still exists and such bundles will need to be rebuilt. The malware seemingly only targets cryptocurrency transactions and wallets such as MetaMask. npm removed the offending package from the registry over the course of the day on 8 September. On 13 September, the package owner published new patch versions to help cache-bust those using private registries who might still have the compromised version cached. This issue has been resolved in 2.1.2.
