The Page Builder by SiteOrigin plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 2.33.5 via the locate_template() function. This makes it possible for authenticated attackers, with Contributor-level access and above, to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.

The SiteOrigin Widgets Bundle plugin for WordPress is vulnerable to unauthorized arbitrary shortcode execution in all versions up to, and including, 1.70.4. This is due to a missing capability check on the `siteorigin_widget_preview_widget_action()` function which is registered via the `wp_ajax_so_widgets_preview` AJAX action. The function only verifies a nonce (`widgets_action`) but does not check user capabilities. This makes it possible for authenticated attackers, with Subscriber-level access and above, to execute arbitrary shortcodes by invoking the `SiteOrigin_Widget_Editor_Widget` via the preview endpoint. The required nonce is exposed on the public frontend when the Post Carousel widget is present on a page, embedded in the `data-ajax-url` HTML attribute.

The SiteOrigin Widgets Bundle plugin for WordPress is vulnerable to Stored Cross-Site Scripting via several parameters in all versions up to, and including, 1.58.7 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor access or above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Affected parameters include: $instance['fonts']['title_options']['tag'], $headline_tag, $sub_headline_tag, $feature['icon'].

The SiteOrigin Widgets Bundle plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the onclick parameter in all versions up to, and including, 1.58.3 due to insufficient input sanitization and output escaping.
