CVE-2026-9852

CVE-2026-9852 - UNKNOWN Severity Vulnerability

A CSV injection vulnerability exists in SYS600. Injected malicious formulas can add or modify data to the spreadsheet, insert links, exfiltrate data, and in some cases, depending on how the user has their environment configured, execute malicious code on the user’s machine. To exploit this issue attackers would need a way to create arbitrary log messages. This could be achieved through normal functionality via SCIL scripts, a log injection vulnerability, or via the SYS600 broker. This vulnerability affects all Windows users regardless of their privilege level who can run the Notify service and export the log.

CVE-2026-76797

CVE-2026-76797 - MEDIUM Severity Vulnerability

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.
