CVE-2026-44969: CWE-532: Insertion of Sensitive Information into Log File in dbt-labs dbt-mcp
dbt-mcp versions prior to 1.17.1 log sensitive information such as sql_query, vars, and node_selection in plaintext to log files when file logging is enabled. This logging occurs at INFO level before tool calls and at ERROR level on exceptions, potentially exposing sensitive data. The issue is fixed in version 1.17.1.
AI Analysis
Technical Summary
The vulnerability in dbt-mcp (CVE-2026-44969) involves the insertion of sensitive information into log files. Specifically, the DbtMCP.call_tool() function logs the raw arguments dictionary, including sensitive fields like sql_query, vars, and node_selection, at INFO and ERROR levels. When file logging is enabled via DBT_MCP_SERVER_FILE_LOGGING=true, these logs are written to dbt-mcp.log without automatic rotation or deletion, risking exposure of sensitive data. This behavior was corrected in version 1.17.1.
Potential Impact
Sensitive information is recorded in plaintext in log files, which could lead to unauthorized disclosure if log files are accessed by unauthorized parties. The CVSS score of 2.5 reflects a low severity impact with limited confidentiality impact and no integrity or availability impact.
Mitigation Recommendations
Upgrade to dbt-mcp version 1.17.1 or later, where this logging behavior has been fixed. Until upgraded, avoid enabling file logging with DBT_MCP_SERVER_FILE_LOGGING=true to prevent sensitive data from being written to logs.
