Elementor Website Builder – more than just a page builder

The Elementor Website Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the _elementor_data meta field in versions up to, and including, 4.0.4. This is due to insufficient input sanitization when processing form-encoded REST API requests. The plugin registers the _elementor_data meta field with show_in_rest but omits a sanitize_callback, relying instead on a rest_pre_insert_post filter (sanitize_post_data function) that only sanitizes JSON-encoded request bodies. When a contributor sends a form-encoded PATCH request to the WordPress REST API, the json_decode() call on the raw body returns null, causing all sanitization to be skipped. The unsanitized data is then stored via update_post_meta() and later output without escaping through multiple widget sinks including the HTML widget's print_unescaped_setting() function. 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 Elementor Website Builder – More Than Just a Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via several widget parameters in all versions up to, and including, 3.35.5 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 Elementor Website Builder plugin for WordPress is vulnerable to Incorrect Authorization to Sensitive Information Exposure in all versions up to, and including, 3.35.7. This is due to a logic error in the is_allowed_to_read_template() function permission check that treats non-published templates as readable without verifying edit capabilities. This makes it possible for authenticated attackers, with contributor-level access and above, to read private or draft Elementor template content via the 'template_id' supplied to the 'get_template_data' action of the 'elementor_ajax' endpoint.

The Elementor Website Builder plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in versions up to, and including, 3.35.5. This makes it possible for authenticated attackers, with author-level access and above, to perform an unauthorized action.

The Elementor Website Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.35.5 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 Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Text Path widget in all versions up to, and including, 3.33.3 due to insufficient neutralization of user-supplied input used to build SVG markup inside the widget. 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 Elementor Website Builder – More Than Just a Page Builder plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to, and including, 3.33.0. This makes it possible for authenticated attackers, with Contributor-level access and above, to perform an unauthorized action.

The Elementor plugin for WordPress is vulnerable to Arbitrary File Read in all versions up to, and including, 3.30.2 via the Import_Images::import() function due to insufficient controls on the filename specified. This makes it possible for authenticated attackers, with administrator-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.

The Elementor Website Builder – More Than Just a Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the data-text DOM element attribute in Text Path widget in all versions up to, and including, 3.30.2 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. This attack affects only Chrome/Edge browsers

The Elementor Website Builder – More Than Just a Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'elementor-element' shortcode in all versions up to, and including, 3.29.0 due to insufficient input sanitization and output escaping on user supplied attributes. 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. This only impacts sites with 'Element Caching' enabled.
