CVE-2026-1231: Beaver Builder Page Builder – Drag and Drop Website Builder <= 2.10.0.5 - Authenticated (Custom+) Missing Authorization to Stored Cross-Site Scripting via Global Settings

The Beaver Builder Page Builder – Drag and Drop Website Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `js` Global Settings parameter in all versions up to, and including, 2.10.0.5 due to missing capability checks on save_global_settings() function and insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Custom-level access and above who have been granted beaver builder access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Security readout for executives and security teams

Plain-English summary

CVE-2026-1231 affects the Beaver Builder WordPress plugin through version 2.10.0.5. A logged-in user with Custom-level or higher Beaver Builder access could save malicious script in global settings. That script may run when users visit affected pages, creating risk to site administrators and visitors.

Executive priority

Treat as a timely WordPress plugin remediation item, especially on sites with many content users or delegated builder access. It is not currently evidenced as actively exploited, but stored XSS can damage trust and expose sessions or sensitive page data.

Technical view

The issue is stored cross-site scripting in the `js` Global Settings parameter. Sources attribute it to missing capability checks in `save_global_settings()` plus insufficient sanitization and output escaping. The CVSS 3.1 score is 6.4, with network access, low complexity, low privileges, no user interaction, and changed scope.

Likely exposure

Exposure is likely limited to WordPress sites running Beaver Builder Page Builder up to and including 2.10.0.5, where authenticated users have been granted Beaver Builder access at Custom level or above.

Exploitation context

The CVE is not listed as KEV, and the provided sources do not cite active exploitation. Exploitation requires an authenticated account with specific Beaver Builder access, but stored XSS can affect later page viewers without further attacker interaction.

Researcher notes

The public record identifies affected versions and root cause but does not provide a fixed version in the supplied bundle. Focus review on authorization around global settings saves and output handling for the JavaScript setting. Avoid assuming unauthenticated impact.

Mitigation direction

  • Check vendor and WordPress plugin guidance for a fixed Beaver Builder version.
  • Update Beaver Builder if a patched version is available for your site.
  • Restrict Beaver Builder access to trusted users only.
  • Review and remove unexpected JavaScript from Beaver Builder global settings.
  • Audit accounts with Custom-level or higher Beaver Builder permissions.

Validation and detection

  • Inventory WordPress sites using Beaver Builder Page Builder.
  • Confirm installed plugin versions are above 2.10.0.5 or otherwise vendor-confirmed safe.
  • Review Beaver Builder access grants for non-administrator users.
  • Inspect global settings for unauthorized or unusual JavaScript entries.
  • Check security logs for suspicious authenticated settings changes.
