Descripción técnica

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.

———ApostropheCMS is an open-source Node.js content management system, and sanitize-html provides a simple HTML sanitizer with a clear API. From version 1.9.0 until version 2.17.7, packages/sanitize-html/index.js validates an animation value attribute as one flat URL and does not recognize that attributeName selecting href or xlink:href gives the sibling values, from, to, or by attribute SVG SMIL URL semantics. In configurations that allow the animate, animateColor, animateMotion, animateTransform, or set elements, a values list can begin with a safe fragment and contain a later executable destination that survives allowedSchemesAppliedToAttributes checking. When the sanitized SVG is rendered, the browser can copy that later destination into the live link, and a victim who activates the link can execute script in the application's origin. This issue is fixed in version 2.17.7.12h
