{"id":"CVE-2026-80210","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-80210","summary":"FrontAccounting through 2.4.20 generates a CSRF token in end_form() in includes/ui/ui_controls.inc and embeds it as the _token hidden field in every form it renders, but only admin/users.php…","details":"FrontAccounting through 2.4.20 generates a CSRF token in end_form() in includes/ui/ui_controls.inc and embeds it as the _token hidden field in every form it renders, but only admin/users.php and admin/change_current_user_password.php call check_csrf_token() to validate it. No financial transaction handler validates the token, including gl/gl_journal.php, gl/gl_bank.php, purchasing/supplier_invoice.php, sales/customer_invoice.php, sales/customer_payments.php and admin/company_preferences.php, so those endpoints act on POST data with no origin check. An attacker who gets an authenticated user to load a page under attacker control can auto-submit a cross-origin form to any of them and have the forged journal entry, invoice, customer payment, bank transaction or company configuration change recorded under the victim's session.","published":"2026-08-27T17:20:50.573","modified":"2026-08-27T17:20:50.573","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/FrontAccountingERP/FA"},{"type":"WEB","url":"https://github.com/FrontAccountingERP/FA/blob/9464a3ffef03c139d9396e697bce9a0a9f131a72/includes/ui/ui_controls.inc#L89"},{"type":"WEB","url":"https://github.com/geo-chen/oss/blob/main/FA.md#finding-1-cross-site-request-forgery-on-financial-transaction-forms-in-frontaccounting"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/frontaccounting-through-2.4.20-cross-site-request-forgery-on-financial-transaction-forms"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-27T17:20:50.573"}}
