CVE-2026-44970: dbt mcp server — Exploit & Fix

Description

dbt-mcp is a Model Context Protocol server for interacting with dbt. Prior to 1.17.1, DefaultUsageTracker.emit_tool_called_event() in src/dbt_mcp/tracking/tracking.py serialized every MCP tool call's complete arguments dictionary and sent it through dbtlabs_vortex.producer.log_proto without redaction, including sql_query from show, vars from run, build, and test, and node_selection from compile, while usage_tracking_enabled in settings.py enabled telemetry by default unless DBT_SEND_ANONYMOUS_USAGE_STATS=false or DO_NOT_TRACK=1 was set. This issue is fixed in version 1.17.1.
