The Live Composer \u2013 Free WordPress Website Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via ‘dslc_module_downloads_output’ Shortcode Content in all versions up to, and including, 2.1.21 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 save-time wp_kses_post check is bypassed because the payload is stored as a serialized string containing no HTML tags for kses to tokenize, and the shortcode callback re-emits attacker-controlled values \u2014 including view_all_link (href attribute), main_heading_title (h2 body), button_text (anchor body), and button_inline_svg (anchor body) \u2014 without any escaping at render time.<\/p>\n","protected":false},"excerpt":{"rendered":"
