Administrator session compromise via unescaped date attribute
Published Dec 2, 2022 · Updated Apr 8, 2026
Reflected XSS in Prasunsen Chained Quiz 1.3.2.3 and earlier allows remote attackers to run scripts via the chainedquiz_list date parameter. The completed-results view places the sanitized date request value into an HTML attribute without context-appropriate attribute escaping. Exploitation requires a logged-in administrator to open an attacker-crafted link; the script then runs in that administrator's browser session and can perform privileged site actions.
