CVE-2026-19324

Local file disclosure via unchecked static path

Published Aug 9, 2026 · Updated Aug 9, 2026

Path traversal in HelloGGX shadcn-vue-mcp 1.0.1 allows local users to read files through its loopback callback server. The server joins the request pathname to its previewer directory and passes the result to stat() and readFile() without checking that the resolved path remains contained. Any local process or local web content able to request the 127.0.0.1 service can retrieve files readable by the Node.js process.
