The Live Composer – Free WordPress Website Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via dslc_module_projects_output Shortcode in all versions up to, and including, 2.1.19 due to insufficient input sanitization and output escaping. 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. WordPress's shortcode-aware kses handling preserves the serialized shortcode body as a placeholder before content filtering runs, allowing attacker-controlled values such as view_all_link, main_heading_link_title, main_filter_title_all, and button_text to reach render-time sinks entirely unescaped.
