Reflected XSS via unvalidated input echo
Published May 10, 2022 · Updated Apr 8, 2026
Reflected XSS in wp_js_admin in Halmat Ferello WP JS 2.0.6 and earlier allows remote attackers to execute script via crafted input. The wp-js.php handler passes unvalidated request input to wp_js_admin, which echoes the value into the generated page without output encoding. Exploitation requires a user to follow an attacker-controlled request, and the resulting script runs in that user's WordPress browser context.
