MongoDB BI Connector ODBC driver may write outside an allocated buffer when handling oversized catalog object names

Published Aug 12, 2026 CVSS 4.0 · 9.5 Critical EPSS < 1% KEV · Not listed
Description
The MongoDB BI Connector ODBC Driver may write outside the bounds of a fixed-size buffer when an application supplies an unusually long catalog, schema, or object name to a metadata retrieval function. This may result in memory corruption within the calling application's process, leading to abnormal termination and, under certain conditions, the potential for arbitrary code execution.
