- CVE-2026-103354, 4 Oct 2026
- Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Liquid Web / StellarWP Gutenberg Blocks by Kadence Blocks kadence-blocks allows Stored XSS.This issue affects Gutenberg Blocks by Kadence Blocks: from n/a through 3.7.11.1. CVE record
- CVE-2026-18062, 1 Aug 2026
- The Kadence Blocks - Page Builder Toolkit for Gutenberg Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Identity Block Inner Image Content in all versions up to, and including, 3.7.8.1 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 vulnerability is only triggerable when the block's urlTransparent attribute is set to a non-empty value, as this is a required precondition for the vulnerable code path in build_html() to be reached. CVE record
- CVE-2026-18435, 1 Aug 2026
- The Kadence Blocks - Page Builder Toolkit for Gutenberg Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'toggleIcon' Block Attribute in all versions up to, and including, 3.7.8 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. CVE record
- CVE-2026-15286, 10 Jul 2026
- The Gutenberg Blocks with AI by Kadence WP - Page Builder Features plugin for WordPress is vulnerable to unauthorized post publication in all versions up to, and including, 3.5.32 due to a misconfigured capability check on the 'get_items_permission_check' function permission callback of the 'process_pattern' REST API endpoint. This makes it possible for authenticated attackers, with Contributor-level access and above, to create and immediately publish posts of any type (including pages), bypassing the standard WordPress review workflow where contributors must submit posts for administrator approval. CVE record
- CVE-2026-12902, 1 Jul 2026
- The Kadence Blocks - Page Builder Toolkit for Gutenberg Editor plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.7.7. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to create arbitrary Media Library attachments by downloading remote images to the site's uploads directory via wp_upload_bits() and wp_insert_attachment(), bypassing the upload_files capability boundary. CVE record
- CVE-2026-12904, 1 Jul 2026
- The Kadence Blocks - Gutenberg Blocks for Page Builder Features plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to and including 3.7.7. This is due to a mismatch between the object used for authorization and the object actually accessed in the Optimize_Rest_Controller's create_item(), get_item(), delete_item(), and bulk_delete_items() endpoints - authorization is checked via current_user_can('edit_post'/'delete_post', $post_id) against the user-supplied post_id, while the storage layer keys analysis records on sha256($post_path) from a separately supplied, attacker-controlled post_path parameter, with no enforcement that post_path corresponds to post_id. This makes it possible for authenticated attackers, with Contributor-level access and above, to read or delete optimizer analysis records belonging to posts owned by other users by submitting their own post_id (which passes the capability check) together with the victim post's path. CVE record
- CVE-2026-11357, 18 Jun 2026
- The Kadence Blocks - Page Builder Toolkit for Gutenberg Editor plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.7.5 via the editor_assets_variables. This makes it possible for authenticated attackers, with contributor-level access and above, to extract the site's connected Kadence account license key, license owner email, api_key, api_email, and license domain from the browser console by inspecting window.kadence_blocks_params.proData. Exploitation requires only that an administrator has previously connected a valid Kadence license; the full credential bundle is then readable by any Contributor-level user from the block editor client context without any server-side request manipulation. CVE record
- CVE-2026-2826, 4 Apr 2026
- The Kadence Blocks - Page Builder Toolkit for Gutenberg Editor plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.6.3. This is due to the plugin not properly verifying that a user has the `upload_files` capability in the `process_pattern` REST API endpoint. This makes it possible for authenticated attackers, with contributor level access and above, to upload images to the WordPress Media Library by supplying remote image URLs that the server downloads and creates as media attachments. CVE record
- CVE-2026-2633, 18 Feb 2026
- The Gutenberg Blocks with AI by Kadence WP plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.6.1. This is due to a missing capability check in the `process_image_data_ajax_callback()` function which handles the `kadence_import_process_image_data` AJAX action. The function's authorization check via `verify_ajax_call()` only validates `edit_posts` capability but fails to check for the `upload_files` capability. This makes it possible for authenticated attackers, with Contributor-level access and above, to upload arbitrary images from remote URLs to the WordPress Media Library, bypassing the standard WordPress capability restriction that prevents Contributors from uploading files. CVE record
- CVE-2026-1857, 18 Feb 2026
- The Gutenberg Blocks with AI by Kadence WP plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 3.6.1. This is due to insufficient validation of the `endpoint` parameter in the `get_items()` function of the GetResponse REST API handler. The endpoint's permission check only requires `edit_posts` capability (Contributor role) rather than `manage_options` (Administrator). This makes it possible for authenticated attackers, with Contributor-level access and above, to make server-side requests to arbitrary endpoints on the configured GetResponse API server, retrieving sensitive data such as contacts, campaigns, and mailing lists using the site's stored API credentials. The stored API key is also leaked in the request headers. CVE record
- CVE-2026-2608, 17 Feb 2026
- The Kadence Blocks - Page Builder Toolkit for Gutenberg Editor plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to, and including, 3.5.32. This makes it possible for authenticated attackers, with Contributor-level access and above, to perform an unauthorized action. CVE record
