CVE-2026-81532 — BI Connector ODBC Driver Improper Bounds Checking on Cursor Name Leading to Memory Corruption

CVE-2026-81532

BI Connector ODBC Driver Improper Bounds Checking on Cursor Name Leading to Memory Corruption PUBLISHED

Description (CNA)

A user able to submit SQL through an application using the MongoDB Connector for BI ODBC driver can supply a positioned-cursor statement whose cursor name exceeds the size of an internal fixed-length buffer. Because the name length is not bounded before the driver builds its diagnostic message, memory adjacent to that buffer is overwritten with user-supplied content. This can terminate the hosting application process and may allow unintended code to run within it.
