At a glance
CVE-2025-10498 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Ninja Forms WordPress plugin, affecting versions <= 3.12.0. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 3.12.1; sites on affected versions should update now. Disclosed September 2025, reported by Nguyen Ngoc Quang Bach (maysbachs).
Vulnerability Overview
The Ninja Forms – The Contact Form Builder That Grows With You plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.12.0. This is due to missing or incorrect nonce validation when exporting CSV files. This makes it possible for unauthenticated attackers to delete those files granted they can trick an administrator into performing an action such as clicking on a link.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Ninja Forms <= 3.12.0 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Ninja Forms the fix is 3.12.1: builds <= 3.12.0 are affected, anything from 3.12.1 onward is not.
Remediation
Update to version 3.12.1, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Ninja Forms: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Ninja Forms 3.12.1 closes this, and updating the plugin is the step that ends it.
