Vulnerability Details
CVE-ID: CVE-2025-12934
Affected Software: Beaver Builder Page Builder
Affected Versions: 0 through 2.9.4.1
Vulnerability: This flaw, categorized as CWE-862, stems from a missing capability check on the duplicate_wpml_layout function. It allows authenticated attackers with Subscriber-level access or higher to perform unauthorized content updates and deletions on posts created with the builder.
Business Impact
The ability for low-privileged users to modify or overwrite arbitrary posts can lead to unauthorized data disclosure, including private or password-protected information. With a CVSS score of 8.1, this high-severity vulnerability poses a critical risk to site content integrity and confidentiality, potentially leading to unauthorized data loss or the exposure of proprietary information.
Remediation Plan
Immediate Action: Update the Beaver Builder plugin to the latest available version (beyond 2.9.4.1) provided by the vendor to implement the required capability checks.
Proactive Monitoring: Review audit logs for unusual post modification activity or unauthorized content changes initiated by accounts with low-level privileges.
Compensating Controls: Deploy a Web Application Firewall (WAF) to monitor and block suspicious requests targeting the plugin functionality until the software can be patched.
Exploitation Status
Public Exploit Available: Unknown
Analyst Notes: As of December 25, 2025, there is no public information indicating active exploitation or a public proof-of-concept for this vulnerability. The flaw is inherently exploitable by any registered user on a WordPress site where the plugin is enabled, making it a high-priority item for administrators to address.
Analyst Recommendation
Given the high CVSS score and the ease with which low-privileged users can execute this attack, organizations should prioritize updating the Beaver Builder plugin immediately. Failure to apply the patch leaves site content vulnerable to unauthorized modification and potential data loss, which could have severe consequences for business operations and data privacy.
