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.
