This flaw enables unauthenticated attackers to manipulate critical form data by submitting values that do not correspond to any valid, pre-configured options within ListSelect or ListRadio fields. Exploitation involves tampering with the payload sent to the plugin's \u003ccode\u003eajax submit\u003c/code\u003e endpoint. The \u003ccode\u003eget_calc_value()\u003c/code\u003e method, responsible for processing form calculations, fails to properly validate these inputs, allowing attacker-controlled numeric values to influence calculations. This oversight can lead to the manipulation of payment totals, potentially reducing them to zero or any arbitrary figure, thereby undermining the intended pricing logic and posing a direct financial threat to website operators.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn unauthenticated attacker identifies a target WordPress website utilizing the Ninja Forms plugin, version 3.14.8 or prior.\u003c/li\u003e\n\u003cli\u003eThe attacker locates a form on the website that incorporates ListSelect or ListRadio fields designed to influence calculations or payment totals.\u003c/li\u003e\n\u003cli\u003eThe attacker intercepts or crafts a legitimate form submission payload destined for the \u003ccode\u003e/wp-admin/admin-ajax.php\u003c/code\u003e endpoint, specifically targeting the \u003ccode\u003eaction=nf_ajax_submit\u003c/code\u003e request.\u003c/li\u003e\n\u003cli\u003eThe attacker modifies the intercepted payload to inject arbitrary numeric values into form fields that are meant to be ListSelect or ListRadio choices, even if these values are not part of the form's legitimate configuration.\u003c/li\u003e\n\u003cli\u003eThe maliciously crafted payload is then sent to the \u003ccode\u003eajax submit\u003c/code\u003e endpoint of the vulnerable Ninja Forms plugin.\u003c/li\u003e\n\u003cli\u003eDue to the improper input validation vulnerability, the plugin's \u003ccode\u003eget_calc_value()\u003c/code\u003e method processes these attacker-controlled numeric values as legitimate inputs.\u003c/li\u003e\n\u003cli\u003eThis processing results in the manipulation of subsequent form calculations, including payment totals.\u003c/li\u003e\n\u003cli\u003eThe attacker successfully bypasses the website's configured pricing logic, potentially acquiring goods or services at a reduced or zero cost.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eThe successful exploitation of CVE-2026-65052 can lead to severe financial consequences for organizations using the Ninja Forms WordPress plugin for e-commerce or donation collection.
