CVE-2025-12782: Critical Vulnerability in Beaver Builder Plugin Allows Layout Disruption

Overview

CVE-2025-12782 details an authorization bypass vulnerability found in the Beaver Builder – WordPress Page Builder plugin. This vulnerability affects all versions up to and including 2.9.4. It allows authenticated attackers with Contributor-level access or higher to disable the Beaver Builder layout on arbitrary posts and pages. This can lead to significant content integrity issues and disruption of the intended layout.

Technical Details

The vulnerability resides within the disable() function of the Beaver Builder plugin. The plugin fails to properly verify a user’s authorization before allowing them to disable the Beaver Builder layout on a specific post or page. This lack of proper authorization checks means that an attacker with even a low-level user account (Contributor or higher) can manipulate the layout, potentially removing key content or altering the appearance of important pages.

CVSS Analysis

The vulnerability has a CVSS score of 4.3 (MEDIUM).

• CVSS Vector: (Calculation details would be here if available, based on impact and exploitability)

While the CVSS score is MEDIUM, the potential impact on website appearance and content integrity should not be underestimated. Even seemingly minor disruptions can damage a website’s credibility and user experience.

Possible Impact

Successful exploitation of this vulnerability could lead to several negative consequences:

• Content Disruption: Attackers can remove or alter key content on important pages, misleading visitors.
• Layout Damage: The intended layout of the website can be completely broken, creating a negative user experience.
• SEO Impact: Changes to content and layout can negatively impact the website’s search engine ranking.
• Reputational Damage: A compromised website can damage the organization’s reputation and lose customer trust.

Mitigation and Patch Steps

The vulnerability has been patched in versions later than 2.9.4. To mitigate this vulnerability, take the following steps:

1. Update Beaver Builder: Immediately update the Beaver Builder plugin to the latest available version. This can be done through the WordPress admin panel under Plugins > Installed Plugins.
2. Verify User Roles: Review user roles and permissions to ensure that only trusted users have administrator-level access. Limit contributor-level access to trusted individuals as well.
3. Monitor Activity: Monitor website activity for any suspicious changes to page layouts or content.
