CVE-2026-30615 is a prompt injection vulnerability in Windsurf 1.9544.26. When Windsurf processes attacker-controlled HTML content, embedded malicious instructions can influence the application to modify the local MCP configuration and automatically register a malicious MCP STDIO server. Because the registered MCP server is then executed locally, this results in arbitrary command execution on the victim system without further user interaction. The issue is described as a zero-click path in which attacker-controlled content rewrites local MCP configuration rather than requiring the user to manually approve or install the malicious server.
