CVE-2026-65052Network attack vector

Payment total tampering via fail-open list validation

Published Jul 21, 2026 · Updated Jul 21, 2026

Improper input validation in Saturday Drive Ninja Forms 3.14.8 and earlier allows remote attackers to alter calculation and payment totals. The get_calc_value() method returns an unconfigured ListSelect or ListRadio value from an AJAX submission as its calculation value instead of rejecting it. Unauthenticated access is sufficient to set totals to zero or arbitrary numeric amounts, bypassing administrator-configured pricing logic.
