CVE-2026-80210Network attack vector

Forged financial transactions via unchecked CSRF tokens

Published Aug 27, 2026 · Updated Aug 27, 2026

Cross-site request forgery in FrontAccounting through 2.4.20 allows remote attackers to forge financial transactions via a victim's session. Financial and administrative POST handlers do not call check_csrf_token(), so they accept cross-origin requests without validating the generated _token. The victim must be authenticated and load attacker-controlled content; forged entries and configuration changes run with the victim's permissions.
