## Description

The Events Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'tags_label', 'tag_label', 'categories_label' and 'category_label' attributes of the event_search_form (events_search) shortcode in versions 6.4.7 up to, and including, 7.4.8. This is due to insufficient output escaping: the search form tag and category templates print these values into data-default and data-label HTML attributes without escaping them. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that execute whenever a user accesses an injected page.
