CVE-2026-18888

MongoDB BI Connector ODBC driver may write outside an allocated buffer when retrieving large floating point values as character data PUBLISHED

Description (CNA)

The MongoDB BI Connector ODBC Driver converts floating point column values into text without checking that the result fits within the destination buffer. When an application reads a sufficiently large floating point value as text, the driver may write beyond the end of that buffer and corrupt adjacent memory. A user who can store data in a collection read through the BI Connector could use this to crash the application performing the read.
