Divi <= 4.27.6 - Authenticated (Contributor+) Stored Cross-Site Scripting via Dynamic Content (Legacy JSON Format) Shortcode
The Divi theme for WordPress is vulnerable to Stored Cross-Site Scripting via the Dynamic Content feature's legacy JSON format in all versions up to, and including, 4.27.6. This is due to two compounding flaws: (1) the save-time sanitization filter et_builder_sanitize_dynamic_content_fields() only searches for dynamic content markers in the @ET-DC@...@ format, but the rendering engine also supports a legacy JSON format that is silently converted at render time, completely bypassing the save-time filter, and (2) the post_meta_key resolver in et_builder_filter_resolve_default_dynamic_content() does not apply wp_kses_post() to the resolved meta value when enable_html is set to on, passing raw get_post_meta() output directly to the page. 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.
