{"id":"CVE-2026-50179","summary":"Actual: CSV Formula Injection in Transaction Export via Imported Payee/Notes Fields","details":"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.","aliases":["GHSA-xqjm-27pc-rvwm"],"modified":"2026-07-15T01:49:04.701932141Z","published":"2026-07-07T20:58:16.074Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50179.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-1236"]},"references":[{"type":"WEB","url":"https://github.com/actualbudget/actual/releases/tag/v26.6.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50179.json"},{"type":"ADVISORY","url":"https://github.com/actualbudget/actual/security/advisories/GHSA-xqjm-27pc-rvwm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50179"},{"type":"FIX","url":"https://github.com/actualbudget/actual/commit/068185751c03b42e726e3c60b718413d5f96c306"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/actualbudget/actual","events":[{"introduced":"0"},{"fixed":"068185751c03b42e726e3c60b718413d5f96c306"},{"fixed":"3a730c160f8e6e4ea68f191d075a46bbbb7073d8"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"26.6.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v26.4.0","v26.3.0","v26.2.0","v26.1.0","v25.12.0","v25.11.0","v25.10.0","v25.9.0","v25.8.0","v25.7.1","v25.7.0","v25.6.1","v25.6.0","v25.5.0","v25.4.0","v25.3.0","v25.2.0","v25.1.0","v24.12.0","v24.11.0","v24.10.0","v24.9.0","v24.8.0","v24.7.0","v24.6.0","v24.5.0","v24.4.0","v24.3.0","v24.2.0","v24.1.0","v23.12.0","v23.11.0","v23.10.0","v23.9.0","v23.8.1","v23.8.0","v23.7.2","v23.7.1","v23.7.0","v23.6.0","v23.5.0","v23.4.2","v23.4.1","v23.4.0","v23.3.2","v23.3.0","v23.2.9","v23.2.5","v23.1.12","v22.12.9"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-50179.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N"}]}
