Overview

CVE-2026-50179 is a medium-severity vulnerability. It was published on July 7, 2026 and has a CVSS 3.1 base score of 4.2 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.2, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
