Client-side script execution via reflected current_page input

Published May 17, 2026 · Updated May 17, 2026

Cross-site scripting in Tribal Systems Zenario 7.0 allows remote attackers to execute JavaScript through a crafted POST request. The ajax.php refreshPlugin handler places the current_page parameter into an HTML id attribute without neutralizing script markup. No account is required, but a victim must render the returned content; execution is confined to the victim browser's Zenario origin.
