Description
The Events Made Easy plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the event list filter parameters (such as 'eme_city_filter', 'eme_cat_filter' or 'eme_scope_filter') in all versions up to, and including, 3.3.2, due to insufficient output escaping. On paged event lists the filter values are only passed through sanitize_text_field, which keeps quotes, then added to the previous and next page links with add_query_arg, which does not encode them, and printed into single-quoted href attributes without esc_url(). This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
