CVE-2026-16788
Medium · 6.4
CWE-79 Sep 1, 2026
Live Composer <= 2.1.19 - Authenticated (Contributor+) Stored Cross-Site Scripting via dslc_module_projects_output Shortcode
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.

Live Composer <= 2.1.19 - Authenticated (Contributor+) Stored Cross-Site Scripting via dslc_module_testimonials_output Shortcode
The Live Composer – Free WordPress Website Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via dslc_module_testimonials_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. The injected payload survives save-time wp_kses_post filtering because KSES treats shortcode delimiters as opaque, and the unescaped fields — including main_heading_title, view_all_link, main_heading_link_title, and main_filter_title_all — are only rendered when do_shortcode() executes at page-view time.

Live Composer <= 2.1.19 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'dslc_custom_field' Shortcode
The Live Composer – Free WordPress Website Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'dslc_custom_field' 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.
CVE-2026-13203
Medium · 6.4
CWE-79 Sep 1, 2026
Live Composer <= 2.1.19 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'custom_id' Shortcode Attribute
The Live Composer – Free WordPress Website Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'custom_id' shortcode attribute of the dslc_modules_section and dslc_modules_area shortcodes in versions up to, and including, 2.1.19. This is due to insufficient input sanitization and output escaping on the user-supplied attribute, which is concatenated into the HTML id="" attribute of the rendered <div> element in the dslc_modules_section_front() and dslc_modules_area_front() functions without esc_attr(). 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.
CVE-2025-14071
High · 7.5
CWE-502 Dec 21, 2025
Live Composer – Free WordPress Website Builder <= 2.0.2 - Authenticated (Contributor+) PHP Object Injection via dslc_module_posts_output Shortcode
The Live Composer – Free WordPress Website Builder plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.0.2 via deserialization of untrusted input in the dslc_module_posts_output shortcode. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable plugin, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.

Live Composer – Free WordPress Website Builder <= 2.0.2 - Authenticated (Contributor+) DOM-Based Stored Cross-Site Scripting
The Live Composer – Free WordPress Website Builder plugin for WordPress is vulnerable to multiple Stored Cross-Site Scripting vulnerabilities via DOM manipulation in all versions up to, and including, 2.0.2 due to insufficient input sanitization and output escaping on user-supplied attributes. 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.
