CVE-2026-19003

A data source definition containing an over-length file path setting may cause the MongoDB BI Connector ODBC Driver setup dialog to write outside the bounds of an allocated buffer. The issue stems from an incorrect buffer capacity calculation in the dialog's file and folder selection handling, and is reached only when a user opens the setup dialog for such a data source and initiates a file or folder selection. Depending on build configuration, the result may range from abnormal process termination to, under certain conditions, execution of unintended code in the context of the user running the dialog.

Summary		(es) Una definición de fuente de datos que contiene una configuración de ruta de archivo de longitud excesiva puede hacer que el diálogo de configuración del controlador ODBC de MongoDB BI Connector escriba fuera de los límites de un búfer asignado. El problema se deriva de un cálculo incorrecto de la capacidad del búfer en el manejo de la selección de archivos y carpetas del diálogo, y solo se alcanza cuando un usuario abre el diálogo de configuración para dicha fuente de datos e inicia una selección de archivo o carpeta. Dependiendo de la configuración de compilación, el resultado puede variar desde la terminación anormal del proceso hasta, bajo ciertas condiciones, la ejecución de código no intencionado en el contexto del usuario que ejecuta el diálogo.
