CVE-2026-76797 is a medium-severity code injection vulnerability in MongoDB BI Connector Transition Readiness Report, published on 28 Aug 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official 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.
