CVE-2023-27613Network attack vector

Browser script execution via unescaped p parameter

Published May 29, 2023 · Updated Apr 28, 2026

Reflected XSS in MonitorClick Forms Ada – Form Builder 1.0 and earlier allows remote attackers to run scripts via crafted p parameters. The $page_nav handling reflects the p request value into generated page output without sufficient sanitization or output escaping. Execution requires a user to open an attacker-crafted page; the script then runs in that site's browser origin and can read or change accessible page data.
