CVE-2026-30615: A prompt injection vulnerability in Windsurf 1.9544.26 allows remote attackers to execute arbitrary commands on a victim

Windsurf version 1.9544.26 has a prompt injection vulnerability (a technique where attackers hide malicious instructions in input to trick an AI system) that allows remote attackers to execute arbitrary commands on a victim's computer. When Windsurf processes attacker-controlled HTML content, it can be tricked into automatically registering a malicious MCP STDIO server (a communication interface for running code), giving attackers the ability to run commands without the user's knowledge.
