{"cve":"CVE-2026-33980","nvd":{"published":"2026-03-27T22:16:22.607","modified":"2026-10-26T21:10:00.170","status":"Analyzed","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":8.1},"cwes":["CWE-943"],"references":["https://github.com/pab1it0/adx-mcp-server/commit/0abe0ee55279e111281076393e5e966335fffd30","https://github.com/pab1it0/adx-mcp-server/security/advisories/GHSA-vphc-468g-8rfp","https://github.com/pab1it0/adx-mcp-server/security/advisories/GHSA-vphc-468g-8rfp"],"products":["pab1it0:azure_data_explorer_mcp_server"],"source":"nvd","synced_at":"2026-10-26T21:38:48.864438205+00:00"},"epss":{"cve":"CVE-2026-33980","score":0.00403,"percentile":0.34326,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-vphc-468g-8rfp","url":"https://osv.dev/vulnerability/GHSA-vphc-468g-8rfp","summary":"Azure Data Explorer MCP Server: KQL Injection in multiple tools allows MCP client to execute arbitrary Kusto queries","modified":"2026-07-13T16:43:43.352646701Z","packages":[{"ecosystem":"PyPI","name":"adx-mcp-server","purl":"pkg:pypi/adx-mcp-server","ranges":["<=1.1.0"],"fixed":[]}]},{"id":"PYSEC-2026-2327","url":"https://osv.dev/vulnerability/PYSEC-2026-2327","summary":"Azure Data Explorer MCP Server: KQL Injection in multiple tools allows MCP client to execute arbitrary Kusto queries","modified":"2026-07-13T16:31:37.757999013Z","packages":[{"ecosystem":"PyPI","name":"adx-mcp-server","purl":"pkg:pypi/adx-mcp-server","ranges":["<=1.1.0"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
