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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":4.6},"cwes":["CWE-1236"],"references":["https://github.com/actualbudget/actual/commit/068185751c03b42e726e3c60b718413d5f96c306","https://github.com/actualbudget/actual/pull/7859","https://github.com/actualbudget/actual/releases/tag/v26.6.0","https://github.com/actualbudget/actual/security/advisories/GHSA-7gh7-258j-4mpq","https://github.com/actualbudget/actual/security/advisories/GHSA-7gh7-258j-4mpq"],"products":[],"source":"nvd","synced_at":"2026-10-25T23:44:34.550481224+00:00"},"epss":{"cve":"CVE-2026-46672","score":0.00187,"percentile":0.08241,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-7gh7-258j-4mpq","url":"https://osv.dev/vulnerability/GHSA-7gh7-258j-4mpq","summary":"@actual-app/cli `--format csv` Output Vulnerable to CSV Formula Injection via Custom `escapeCsv` Helper","modified":"2026-09-10T03:50:48.727754371Z","packages":[{"ecosystem":"npm","name":"@actual-app/cli","purl":"pkg:npm/%40actual-app/cli","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).
