Summary
A path traversal vulnerability in o1lab/xmysql (all versions) allows an unauthenticated remote attacker to read and download arbitrary files from the server. The lib/xapi.js file at lines 338 and 424 uses the user-controlled req.query.name parameter in path.join(cwd, name) without sanitization before passing it to res.download, enabling directory traversal via ../ sequences to access sensitive system files.
