Authenticated browser script execution via unescaped form actions
Published May 21, 2026 · Updated May 21, 2026
Reflected XSS in patient.php in Open ISES Tickets CAD before 3.44.2 allows remote authenticated users to execute JavaScript in a victim's browser. The script prints the id and ticket_id GET values into HTML form action URLs without context-appropriate escaping, so crafted attribute content becomes executable markup. Exploitation requires a victim to render an attacker-crafted request while signed in, and the injected script runs in that victim's browser context.
