MongoDB BI Connector ODBC Driver Memory-Safety Issue When Handling Stored Procedure Output Parameters

Assigner: mongodb
Reserved: 05.08.2026 Published: 12.08.2026 Updated: 13.08.2026

An application using the MongoDB BI Connector ODBC Driver may experience a memory-safety issue when processing output parameters from a stored procedure. Triggering this issue requires connecting to an untrusted or impersonated database server that returns crafted metadata. This may result in process termination, disclosure of process memory, or, under certain conditions, arbitrary code execution.
