Technical details

A stored XSS vulnerability exists in the cfturnstile_gravity_shortcode() function due to insufficient sanitization and escaping of the 'id' attribute in the [gravity-simple-turnstile] shortcode. The value is processed with esc_html() and sanitize_text_field() but then emitted via esc_js() in a raw JavaScript context outside string literals, allowing unescaped characters like parentheses and dots to break out and inject arbitrary JavaScript. Authenticated attackers with contributor-level or higher permissions can exploit this to execute scripts when users access injected pages.
