Anatomy of the 1-Click RCE: How a Malicious gatewayUrl Leads to Full Node.js App Compromise

Deep Dive into the 1-Click RCE Vulnerability: Gateway Compromise Risks from gatewayUrl Authentication Token Exfiltration In modern software development and deployment ecosystems, npm packages serve as core dependencies for both frontend and backend development. Their security directly determines the stability of the entire application landscape. Recently, a critical security vulnerability has been disclosed in the clawdbot package within the npm ecosystem—this vulnerability starts with authentication token exfiltration and can ultimately lead to “one-click” Remote Code Execution (1-Click RCE). Even gateways configured to listen only on loopback addresses are not immune to this type of attack. This article will comprehensively dissect …
