CyberRota Analysis
AI-GeneratedThe vulnerability affects the export functionality of the Actual personal finance tool, allowing user-controlled strings to be exported to CSV without proper sanitization. This can lead to the execution of arbitrary formulas in spreadsheet applications like Excel, LibreOffice Calc, or Google Sheets, potentially enabling data exfiltration and manipulation of displayed values. Organizations using versions prior to 26.6.0 should prioritize updating to mitigate the risk of unauthorized data exposure.

Original NVD Description
Actual is a local-first personal finance tool. Prior to 26.6.0, exportToCSV and exportQueryToCSV in packages/loot-core/src/server/transactions/export/export-to-csv.ts pass user-controlled Payee, Notes, Account, and Category strings to csv-stringify with no cast callback and no formula-prefix neutralization. Strings that begin with equals sign, plus, minus, at sign, tab, or carriage return survive verbatim into the exported CSV, and when a recipient opens the file in Excel, LibreOffice Calc, or Google Sheets, the strings are interpreted as formulas, enabling transaction data exfiltration and attacker-chosen spreadsheet display values. This issue is fixed in version 26.6.0.
