## Description

The MongoSQL Transition Readiness Tool writes database and collection names into its generated CSV reports without neutralizing leading characters that spreadsheet applications treat as formulas. A user with write privileges on the cluster can choose a namespace name that is later evaluated as a formula when an operator opens the generated report in a spreadsheet application, which may result in unintended disclosure of report contents or execution of external content on the operator's workstation. Generating a report for the affected namespace and opening it in a spreadsheet application is required.

## Affected Products
