Kubio AI Page Builder

The Kubio plugin for WordPress is vulnerable to Arbitrary File Upload in versions up to and including 2.7.2. This is due to insufficient capability checks in the kubio_rest_pre_insert_import_assets() function, which is hooked to the rest_pre_insert_{post_type} filter for posts, pages, templates, and template parts. When a post is created or updated via the REST API, Kubio parses block attributes looking for URLs in the 'kubio' attribute namespace and automatically imports them via importRemoteFile() without verifying the user has the upload_files capability. This makes it possible for authenticated attackers with Contributor-level access and above to bypass WordPress's normal media upload restrictions and upload files fetched from external URLs to the media library, creating attachment posts in the database.

The Kubio AI Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.7.0 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 Kubio AI Page Builder plugin for WordPress is vulnerable to unauthorized plugin installation due to a missing capability check on the kubio-image-hub-install-plugin AJAX action in all versions up to, and including, 2.6.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to install the Image Hub plugin.

The Kubio AI Page Builder plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 2.5.1 via thekubio_hybrid_theme_load_template function. This makes it possible for unauthenticated attackers 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.
