The CVE-2025-XXXX vulnerability stems from a successful account takeover of the `color-string` npm package maintainer via a phishing attack. The attacker published a malicious version, 2.1.1, which was functionally identical to the legitimate code but included an obfuscated JavaScript payload. This payload was designed to activate exclusively in browser environments. Upon execution, it hooked into the Web3 JavaScript API, specifically targeting and attempting to intercept transactions made through wallets like MetaMask. The malware’s objective was to silently replace the recipient’s cryptocurrency address in a transaction with an address controlled by the attacker, thereby diverting funds without the user’s knowledge. Server-side and CLI uses were not affected as the malicious code was conditionally executed.
