Reflected XSS via unescaped list-table URL
Published Nov 21, 2024 · Updated Apr 8, 2026
Reflected XSS in Theater for WordPress 0.18.6.2 and earlier allows remote attackers to execute scripts through a crafted URL. The list-table code in functions/wpt_productions_list_table.php builds a URL with add_query_arg and emits it without appropriate output escaping. No login is required, but execution depends on a user following the malicious link; the script runs in that user's browser and can read or alter data available to the session.
