Forked VSCode IDEs Expose Developers to Namespace Hijack
⚠ Forked IDEs based on Microsoft VSCode (such as Cursor, Windsurf, Google Antigravity and Trae) retain hardcoded extension recommendations that point to Microsoft's Visual Studio Marketplace. Because these forks use OpenVSX instead, several recommended publisher namespaces were unclaimed, enabling attackers to register them and publish malicious extensions. Supply-chain researchers at Koi claimed affected namespaces and uploaded inert placeholders while coordinating with the Eclipse Foundation to secure the registry.
