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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N","score":4.2},"cwes":["CWE-1236"],"references":["https://github.com/actualbudget/actual/commit/068185751c03b42e726e3c60b718413d5f96c306","https://github.com/actualbudget/actual/releases/tag/v26.6.0","https://github.com/actualbudget/actual/security/advisories/GHSA-xqjm-27pc-rvwm"],"products":[],"source":"nvd","synced_at":"2026-10-25T23:44:34.550481224+00:00"},"epss":{"cve":"CVE-2026-50179","score":0.00286,"percentile":0.20911,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-xqjm-27pc-rvwm","url":"https://osv.dev/vulnerability/GHSA-xqjm-27pc-rvwm","summary":"@actual-app/web has CSV Formula Injection in Transaction Export via Imported Payee/Notes Fields","modified":"2026-09-10T03:51:09.776624296Z","packages":[{"ecosystem":"npm","name":"@actual-app/web","purl":"pkg:npm/%40actual-app/web","ranges":["<26.6.0"],"fixed":["26.6.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
