CVE-2026-19001: MongoDB BI Connector ODBC driver may write outside an allocated buffer when handling oversized catalog object names
Critical · CVSS 9.8 (CVSS 3.1)EPSS 0.54%, 45th percentilePublished Updated Assigner: mongodb
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.
