At a glance

CVE-2025-12426 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the Quiz Maker by AYS WordPress plugin, affecting versions <= 6.7.0.80. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 6.7.0.81; sites on affected versions should update now. Disclosed November 2025, reported by Rafshanzani Suhada.

Vulnerability Overview

The Quiz Maker plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 6.7.0.80. This is due to the plugin exposing quiz answers through the ays_quiz_check_answer AJAX action without proper authorization checks. The endpoint only validates a nonce, but that same nonce is publicly available to all site visitors via the quiz_maker_ajax_public localized script data. This makes it possible for unauthenticated attackers to extract sensitive data including quiz answers for any quiz question.

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, and no interaction from a victim user.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Quiz Maker by AYS <= 6.7.0.80 takes no account at all. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Quiz Maker by AYS the fix is 6.7.0.81: builds <= 6.7.0.80 are affected, anything from 6.7.0.81 onward is not.

Remediation

Update to version 6.7.0.81, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Quiz Maker by AYS 6.7.0.81 closes this, and updating the plugin is the step that ends it.
