CyberRota Analysis
AI-GeneratedThe Live Composer plugin for WordPress is vulnerable to Stored Cross-Site Scripting due to inadequate input sanitization and output escaping in the dslc_module_testimonials_output Shortcode, affecting all versions up to 2.1.19. This flaw allows authenticated attackers with contributor-level access or higher to inject malicious scripts that execute when users access the compromised pages, bypassing standard filtering mechanisms. WordPress site administrators and developers using this plugin should prioritize patching to mitigate potential exploitation risks.
Original NVD Description
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.
