FKIE_CVE-2026-46672

Vulnerability from fkie_nvd - Published: 2026-07-07 21:17 - Updated: 2026-07-08 15:28
Severity
4.6 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N
Summary
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.
