CVE-2026-33980

Full vulnerability record from the local CVENow database.

Description

Azure Data Explorer MCP Server is a Model Context Protocol (MCP) server that enables AI assistants to execute KQL queries and explore Azure Data Explorer (ADX/Kusto) databases through standardized interfaces. Versions up to and including 0.1.1 contain KQL (Kusto Query Language) injection vulnerabilities in three MCP tool handlers: `get_table_schema`, `sample_table_data`, and `get_table_details`. The `table_name` parameter is interpolated directly into KQL queries via f-strings without any validation or sanitization, allowing an attacker (or a prompt-injected AI agent) to execute arbitrary KQL queries against the Azure Data Explorer cluster. Commit 0abe0ee55279e111281076393e5e966335fffd30 patches the issue.

Las versiones hasta la 0.1.1 inclusive contienen vulnerabilidades de inyección de KQL (Kusto Query Language) en tres manejadores de herramientas MCP: ’get_table_schema’, ’sample_table_data’ y ’get_table_details’. El parámetro ’table_name’ se interpola directamente en las consultas KQL a través de f-strings sin ninguna validación o saneamiento, permitiendo a un atacante (o un agente de IA inyectado por prompt) ejecutar consultas KQL arbitrarias contra el clúster de Azure Data Explorer. El commit 0abe0ee55279e111281076393e5e966335fffd30 soluciona el problema."
