CVE-2026-76797

MongoSQL Transition Readiness Tool Improper Neutralization of Formula Elements in Generated Reports

Published Aug 28, 2026 CVSS 4.0 · 5.8 Medium EPSS < 1% KEV · Not listed
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.
