CVE-2026-7642 Details
Description
A vulnerability was detected in pskill9 website-downloader up to 0.1.0. This affects the function download_website of the file src/index.ts of the component MCP Interface. Performing a manipulation of the argument outputPath results in os command injection. The attack may be initiated remotely. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.
A command injection vulnerability has been identified in pskill9 website-downloader versions through 0.1.0. The issue resides in the MCP interface's download_website function within src/index.ts. The vulnerability allows remote attackers to inject operating system commands by manipulating the outputPath argument, which is not properly sanitized before being executed. This flaw could lead to arbitrary command execution with the privileges of the server process, potentially compromising the entire host.
No fixed version is available at this time. As a temporary measure, do not expose the MCP server to untrusted clients, restrict access to the 'download_website' tool to trusted local users, and run the MCP server with a dedicated low-privilege OS account. Once a patch is available, publish a security advisory.
