Vulnerability from github – Published: 2026-08-12 21:31 – Updated: 2026-08-12 21:31

Details

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.

Severity

9.8 (Critical)
