CVE-2026-35228Network attack vector

Malicious SQL execution via unbound helper inputs

Published May 5, 2026 · Updated May 5, 2026

SQL injection in Oracle MCP Server Helper Tool 1.0.1 through 1.0.156 allows remote attackers to execute malicious SQL via HTTP. The dbtools MCP server interpolates externally supplied table names, report fields, model names, and MySQL prompts into SQL text without binding or adequate validation. Oracle's prose describes unauthenticated HTTP access, while its CVSS vector records low privileges and required user interaction; execution uses the helper's database permissions.
