CVE-2026-19001

9.8

MongoDB · BI Connector ODBC Driver

The MongoDB BI Connector ODBC Driver is susceptible to a buffer overflow during metadata retrieval, which may lead to process termination or arbitrary code execution.

Executive summary

A memory corruption vulnerability in the MongoDB BI Connector ODBC Driver, rated as critical, poses a risk of arbitrary code execution for affected applications.

Vulnerability

This is an integer overflow vulnerability that results in a buffer overflow when handling excessively long catalog, schema, or object names. This vulnerability does not require prior authentication to trigger if the application exposes the affected metadata retrieval function to external inputs.

Business impact

Successful exploitation of this flaw could allow an attacker to execute arbitrary code within the context of the calling application, potentially leading to full system compromise. Given the CVSS score of 9.8, the risk to data confidentiality, integrity, and availability is severe, making immediate remediation essential to prevent potential breaches or service disruptions.

Remediation

Immediate Action: Update the MongoDB BI Connector ODBC Driver to version 1.4.9 or later to incorporate the necessary buffer management fixes.

Proactive Monitoring: Review application logs for unexpected termination events or crashes occurring during database metadata retrieval operations.

Compensating Controls: Ensure that applications utilizing this driver implement strict input validation to truncate or sanitize excessively long metadata strings before they reach the driver.

Exploitation status

Public Exploit Available: Unknown.

Analyst recommendation

Organizations using the MongoDB BI Connector ODBC Driver must prioritize updating to the latest version immediately. The potential for arbitrary code execution in this component represents a critical security risk that should be addressed during the current maintenance cycle to ensure the integrity of the database connection layer.
