This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes (notably \u0027title\u0027 and \u0027fixed_link\u0027) which are concatenated directly into single-quoted HTML attributes by the AVALON23_HELPER::draw_html_item() helper without esc_attr() or any other encoding. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page."
