Live › vulnerability › CVE-2026-107758
Go to dashboardThe Colibri Page Builder plugin for WordPress stores attacker-supplied SVG markup through its 'comment' parameter without adequate sanitization, and the front-end script later renders it as HTML. An unauthenticated attacker can inject JavaScript that runs in the browser of any user who opens an affected page, including administrators.

Sites running the Colibri Page Builder WordPress plugin version 1.0.390 or earlier are exposed, because its front-end script runs on every page. Sites that do not have the plugin installed or active can skip this. Unknown whether the sources describe any configuration that reduces exposure.

The Colibri Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 1.0.390 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. The injected payload survives storage because the widened comment allow-list permits SVG elements with arbitrary data-* attributes; execution occurs because colibri.js, enqueued globally on every front-end page, reads the stored data-target value via jQuery.data() — which HTML-entity-decodes it — and passes the resulting string directly into jQuery(), which parses a leading '<' as HTML and fires the embedded event handler.
