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.","state":0,"publishedAt":"2026-07-07T20:58:16.074+00:00","modifiedAt":"2026-07-09T14:42:17.117+00:00","affected":[{"ecosystem":"Vendor product","name":"actual","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"actualbudget\",\n                    \"product\": \"actual\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 26.6.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"MEDIUM"}],"references":["https://github.com/actualbudget/actual/security/advisories/GHSA-xqjm-27pc-rvwm","https://github.com/actualbudget/actual/commit/068185751c03b42e726e3c60b718413d5f96c306","https://github.com/actualbudget/actual/releases/tag/v26.6.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-50179","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-50179","identifiers":["CVE-2026-50179"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
