CVE-2026-2826

Medium

Description

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.
