CVE-2026-30615: n/a
A prompt injection vulnerability in Windsurf 1.9544.26 allows remote attackers to execute arbitrary commands on a victim system. When Windsurf processes attacker-controlled HTML content, malicious instructions can cause unauthorized modification of the local MCP configuration and automatic registration of a malicious MCP STDIO server, resulting in execution of arbitrary commands without further user interaction. Successful exploitation may allow attackers to execute commands on behalf of the user, persist malicious MCP configuration changes, and access sensitive information exposed through the application.
AI Analysis
Technical Summary
This vulnerability involves a prompt injection flaw in Windsurf 1.9544.26 where processing of attacker-supplied HTML content can cause unauthorized changes to the local MCP configuration and registration of a malicious MCP STDIO server. This results in arbitrary command execution on the victim system without further user interaction. The attacker can persist malicious configuration changes and potentially access sensitive data exposed by the application. No CVSS score or remediation details are provided.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary commands on the victim system with the privileges of the user running Windsurf. It also enables persistent malicious changes to the MCP configuration and unauthorized access to sensitive information within the application. This can lead to system compromise and data exposure.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution when processing untrusted HTML content in Windsurf and consider limiting exposure to potentially malicious inputs.
