{"id":"CVE-2026-33980","summary":"Azure Data Explorer MCP Server: KQL Injection in multiple tools allows MCP client to execute arbitrary Kusto queries","details":"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.","aliases":["GHSA-vphc-468g-8rfp"],"modified":"2026-04-10T05:43:19.891187Z","published":"2026-03-27T21:32:57.541Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33980.json","cwe_ids":["CWE-943"],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33980.json"},{"type":"FIX","url":"https://github.com/pab1it0/adx-mcp-server/commit/0abe0ee55279e111281076393e5e966335fffd30"},{"type":"ADVISORY","url":"https://github.com/pab1it0/adx-mcp-server/security/advisories/GHSA-vphc-468g-8rfp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33980"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pab1it0/adx-mcp-server","events":[{"introduced":"0"},{"last_affected":"f81c250370a81ab92e467e054df7d44d497e644e"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"1.1.0"}]}}],"versions":["1.0.1","1.0.3","1.0.4","1.0.5","1.0.6","1.0.7","1.0.8","1.0.9","v1.0.0","v1.0.3","v1.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33980.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L"}]}
