At a glance

CVE-2025-12934 is a high-severity Missing Authorization vulnerability in the Beaver Builder Page Builder WordPress plugin, affecting versions <= 2.9.4.1. It carries a CVSS score of 8.1 (reachable over the network; low attack complexity; high confidentiality, integrity impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 2.9.4.2; sites on affected versions should update now. Disclosed December 2025, reported by Athiwat Tiprasaharn (Jitlada).

Vulnerability Overview

The Beaver Builder – WordPress Page Builder plugin for WordPress is vulnerable to unauthorized access and modification of data due to a missing capability check on the 'duplicate_wpml_layout' function in all versions up to, and including, 2.9.4.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update arbitrary posts with the content of other existing posts, potentially exposing private and password-protected content and deleting any content that is not saved in revisions or backups. Posts must have been created with Beaver Builder to be copied or updated.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity.

CWE-862: Missing Authorization

Beaver Builder Page Builder <= 2.9.4.1 carries this weakness at duplicate_wpml_layout, and reaching it takes an account at Subscriber level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Beaver Builder Page Builder the fix is 2.9.4.2: builds <= 2.9.4.1 are affected, anything from 2.9.4.2 onward is not.

Remediation

Update to version 2.9.4.2, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Beaver Builder Page Builder 2.9.4.2 closes this, and updating the plugin is the step that ends it.
