Description
The Display Eventbrite Events plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'booknow_text' attribute of the [wfea] shortcode and of the Display Eventbrite Events block in all versions up to, and including, 6.9.1, due to insufficient output escaping. The value is filtered only with wp_kses_post(), which keeps double quotes, and is then printed inside the aria-label attribute of the Book Now link. This makes it possible for authenticated attackers, with contributor-level access and above, to break out of the attribute and inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
