Live Composer through 2.1.18 deserializes untrusted input, allowing a Contributor or higher-privileged user to inject PHP objects.

Sep 01, 2026 CVE-2026-16788
Live Composer project shortcodes permit Contributor-level stored cross-site scripting
Live Composer through 2.1.19 preserves the serialized body of dslc_module_projects_output as a shortcode placeholder while content filtering runs. A Contributor or higher can therefore carry values such as view_all_link, main_heading_link_title, main_filter_title_all, and button_text through save-time filtering into unescaped render-time sinks, causing stored script to execute when the page is viewed.

Sep 01, 2026 CVE-2026-16786
Live Composer testimonial shortcodes permit Contributor-level stored cross-site scripting
Live Composer through 2.1.19 treats the dslc_module_testimonials_output shortcode body as opaque during save-time filtering. A Contributor or higher can store malicious values in fields including main_heading_title, view_all_link, main_heading_link_title, and main_filter_title_all; do_shortcode() later renders those values without adequate escaping and executes the script when the page is viewed.

Live Composer custom-field shortcode permits stored cross-site scripting
Live Composer through 2.1.19 insufficiently sanitizes and escapes values rendered by the dslc_custom_field shortcode. A Contributor or higher can store script that executes when another user views the affected page.

Sep 01, 2026 CVE-2026-13203
Live Composer custom ID attributes permit stored cross-site scripting
Live Composer through 2.1.19 concatenates the custom_id attribute from dslc_modules_section and dslc_modules_area shortcodes into a rendered div id without esc_attr() in dslc_modules_section_front() and dslc_modules_area_front(). A Contributor or higher can break out of the attribute and store script that executes when another user views the page.
