Path Traversal in xmysql Database Tool

Publication date: 2026-08-10

Assigner: 309f9ea4-e3e9-4c6c-b79d-e8eb01244f2c

Description
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.

Executive Summary

This is a path traversal vulnerability in the o1lab/xmysql tool. It allows an unauthenticated remote attacker to read and download arbitrary files from the server by exploiting unsanitized user input in file paths. The vulnerable code in lib/xapi.js uses req.query.name directly in path.join(cwd, name) without validation, enabling directory traversal via ../ sequences to access sensitive system files.

Detection Guidance

To detect this vulnerability, check if your system runs o1lab/xmysql by inspecting running Node.js processes or checking installed npm packages globally. Look for suspicious file access patterns in logs, especially requests containing ../ sequences in query parameters targeting endpoints handling file downloads.

Impact Analysis

An attacker could exploit this to access sensitive files on the server, including configuration files, databases, or other confidential data. This could lead to data breaches, unauthorized information disclosure, or further attacks on the system if combined with other vulnerabilities.

Compliance Impact

This vulnerability could lead to unauthorized access to personal or sensitive data, violating GDPR's data protection principles and HIPAA's security requirements. Organizations using xmysql may face compliance violations, legal penalties, and reputational damage if exploited.

Mitigation Strategies

Immediately stop using o1lab/xmysql and migrate to NocoDB as it is the successor project. If you must continue using xmysql temporarily, implement strict input validation for file paths, disable file download endpoints, and ensure no dynamic SQL execution is enabled.
