Administrator-context script execution via unescaped ip parameter
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 through the ip parameter. The chainedquiz_list results page inserts the ip query value into an HTML attribute after sanitize_text_field processing but without esc_attr escaping. An administrator must open the crafted URL; the script then executes in that administrator's browser context and enables creation of another administrator account.
