CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

CVE-2025-66335 is a vulnerability in Apache Doris MCP Server versions earlier than 0.6.1 caused by improper neutralization in the query context handling.

This flaw allows attackers to execute unintended SQL statements by bypassing the intended query validation and access restrictions through the MCP query execution interface.

Versions 0.6.1 and later have fixed this issue and are not affected.

Compliance Impact

The vulnerability in Apache Doris MCP Server allows execution of unintended SQL statements and bypass of intended query validation and access restrictions. This could potentially lead to unauthorized data access or manipulation.

Such unauthorized access or data manipulation may impact compliance with common standards and regulations like GDPR and HIPAA, which require strict controls over data access and protection of sensitive information.

However, the provided information does not explicitly describe the direct effects on compliance with these standards.

Impact Analysis

This vulnerability can allow an attacker to execute unintended SQL statements on the affected Apache Doris MCP Server.

By bypassing query validation and access restrictions, attackers may gain unauthorized access to data or perform unauthorized actions within the database.

Such unauthorized actions could lead to data leakage, data corruption, or other security breaches depending on the database's role and data sensitivity.

Mitigation Strategies

To mitigate this vulnerability, upgrade Apache Doris MCP Server to version 0.6.1 or later, as these versions have addressed the improper neutralization flaw in query context handling.

Avoid using affected versions (from 0.1.0 up to but not including 0.6.1) to prevent execution of unintended SQL statements and bypass of query validation and access restrictions.
