MongoDB BI Connector ODBC Driver: memory corruption

Critical9.5CVE-2026-19001 · Published Aug 12, 2026 · updated Sep 11, 2026

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.
