CVE-2025-58062 Details
Description
LSTM-Kirigaya's openmcp-client is a vscode plugin for mcp developer. Prior to version 0.1.12, when users on a Windows platform connect to an attacker controlled MCP server, attackers could provision a malicious authorization server endpoint to silently achieve an OS command injection attack in the open() invocation, leading to client system compromise. This issue has been patched in version 0.1.12.
A command injection vulnerability has been identified in the LSTM-Kirigaya openmcp-client Visual Studio Code extension, prior to version 0.1.12. This vulnerability occurs when Windows users connect to a maliciously controlled MCP server. Attackers can inject a harmful authorization server endpoint, which is then processed by the extension. This exploitation takes place during the OAuth authorization flow, where the extension uses a command that opens a browser for user authentication. The injected command is executed on the user's operating system, leading to a compromise of the client's system.
Users are advised to update the openmcp-client extension to version 0.1.12 or later, where this vulnerability has been patched.
