{"cve":"CVE-2025-12426","nvd":{"published":"2025-11-19T05:16:02.477","modified":"2026-10-18T20:10:00.110","status":"Analyzed","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-200"],"references":["https://plugins.trac.wordpress.org/browser/quiz-maker/tags/6.7.0.69/includes/class-quiz-maker.php#L393","https://plugins.trac.wordpress.org/browser/quiz-maker/tags/6.7.0.69/public/class-quiz-maker-public.php#L179","https://plugins.trac.wordpress.org/browser/quiz-maker/tags/6.7.0.69/public/class-quiz-maker-public.php#L8490","https://www.wordfence.com/threat-intel/vulnerabilities/id/bc524e3e-9b7c-47ae-ab44-c327b287b81a?source=cve"],"products":["ays-pro:quiz_maker"],"source":"nvd","synced_at":"2026-10-19T22:16:02.354564667+00:00"},"epss":{"cve":"CVE-2025-12426","score":0.00351,"percentile":0.28519,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
