9.8CVE-2025-2294extendthemeskubio ai page builder+1
EPSS score
78.36%
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.
5.4CVE-2025-8487extendthemeskubio ai page builder+1
EPSS score
0.27%
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.
6.1CVE-2024-13516extendthemeskubio ai page builder+1
EPSS score
0.29%
The Kubio AI Page Builder plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'message' parameter in all versions up to, and including, 2.3.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
6.5CVE-2024-39661extendthemeskubio ai page builder+1
EPSS score

Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in ExtendThemes Kubio AI Page Builder.This issue affects Kubio AI Page Builder: from n/a through 2.2.4.
4.3CVE-2026-16779extendthemeskubio ai page builder+1
EPSS score
0.39%
The Kubio AI Page Builder plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.8.5. 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 overwrite front-page configuration options (show_on_front, page_on_front, and page_for_posts), rewrite primary navigation menu items, replace template parts, and overwrite the Kubio global-data post. Although a nonce check via check_ajax_referer() is present, the nonce is unconditionally emitted into window.kubioUtilsData for every user who can load the block editor, making it harvestable by any Contributor and therefore an ineffective authorization barrier.
6.4CVE-2026-14472extendthemeskubio ai page builder+1
EPSS score
0.26%
The Kubio AI Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via kubio/copyright Block Content in all versions up to, and including, 2.8.4 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 bypasses both the WordPress core kses-on-save filter and the plugin's own wp_kses_post() call, because entity-encoded script tags are treated as inert text by kses but are decoded into live HTML by the subsequent html_entity_decode() call in CopyrightBlock::render_template().
5.3CVE-2026-5427extendthemeskubio ai page builder+1
EPSS score
0.47%
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.
7.2CVE-2026-100107extendthemeskubio ai page builder+1
EPSS score
0.31%
The Kubio AI Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 2.9.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
