CyberRota Analysis
AI-GeneratedThe vulnerability affects the @actual-app/cli component of the Actual personal finance app, which improperly handles CSV serialization, allowing for potential formula injection through user-controlled strings in exported CSV files. This can lead to data exfiltration and arbitrary code execution when the CSV is opened in spreadsheet applications like Excel or Google Sheets. Organizations using this app should prioritize updating to version 26.6.0 to mitigate the risk of exploitation.

Original NVD Description
Actual is a local-first personal finance app. Prior to 26.6.0, @actual-app/cli ships a hand-rolled CSV serializer in packages/cli/src/output.ts used whenever the global --format csv option is passed, whose escapeCsv helper only handles RFC 4180 delimiter, quote, and newline escaping and does not neutralize standard CSV formula-injection prefixes. Any CLI command that streams an object array containing user-controlled strings, including transactions list, accounts list, payees list, categories list, tags list, category-groups list, rules list, schedules list, and query, can emit cells that auto-evaluate when the resulting CSV is opened in Excel, LibreOffice Calc, or Google Sheets, enabling data exfiltration and arbitrary formula execution. This issue is fixed in version 26.6.0.
