Understanding the Beaver Builder Authorization Flaw
A security vulnerability has been discovered in the Beaver Builder – WordPress Page Builder plugin, identified as CVE-2025-11726. This issue is categorized as a Missing Authorization flaw, which means the plugin was not properly checking if a user had the necessary permissions to perform certain actions. Specifically, this vulnerability allowed users with lower-level access, such as contributors, to make significant site-wide changes.
Imagine giving someone the keys to a specific room, but they could also unlock the whole house. In this case, an authenticated attacker with contributor-level access or higher could add, change, or even delete global color and background settings. These settings influence the look and feel of all content created with Beaver Builder across your entire website. This could lead to unauthorized visual defacement or disruption of your site’s design.
