Stored XSS via unescaped login callback email

Published Jan 16, 2026 · Updated Jan 16, 2026

Stored XSS in Opinion Stage Quiz Maker, Poll Maker & Survey Maker before 19.6.25 allows remote attackers to inject browser scripts. The public admin-post.php login callback accepts the email parameter without sufficient validation, then emits it into page content without output escaping. No authentication is required to plant the payload; execution requires a victim to view an affected page and occurs in that browser context.
