Memory Corruption in MongoDB BI Connector ODBC Driver

Publication date: 2026-08-12

Last updated on: 2026-08-12

Assigner: MongoDB, Inc.

Description

An application using the MongoDB BI Connector ODBC Driver may experience a memory-safety issue when processing output parameters from a stored procedure. Triggering this issue requires connecting to an untrusted or impersonated database server that returns crafted metadata. This may result in process termination, disclosure of process memory, or, under certain conditions, arbitrary code execution.

Attack-Flow Graph

Executive Summary

This vulnerability is a memory-safety issue in the MongoDB BI Connector ODBC Driver. It occurs when the driver processes output parameters from a stored procedure. An attacker could exploit this by connecting to a malicious database server that sends crafted metadata, potentially causing process termination, memory disclosure, or arbitrary code execution.

Detection Guidance

Detection requires monitoring for crashes or memory corruption when using the MongoDB BI Connector ODBC Driver with untrusted database servers. Check logs for process termination or memory disclosure events during stored procedure execution.

Impact Analysis

If exploited, this vulnerability could allow an attacker to crash the application, leak sensitive memory contents, or execute arbitrary code on your system. This could lead to unauthorized access, data theft, or further compromise of affected systems.

Mitigation Strategies

Immediately update the MongoDB BI Connector ODBC Driver to the latest patched version. Avoid connecting to untrusted or impersonated database servers. Restrict network access to trusted sources only.
