CVE-2026-65568: 
WordPress vulnerability analysis and mitigation

CVE-2026-65568 is a Broken Access Control vulnerability (Missing Authorization) in the Visual Composer Website Builder WordPress plugin affecting versions 45.15.0 and earlier. It allows authenticated users with contributor-level privileges to perform unauthorized actions beyond their intended permission scope. The vulnerability was published on July 27, 2026, and assigned by Patchstack. It carries a CVSS v3.1 base score of 5.0 (Medium) (GitHub Advisory, Patchstack).

The root cause is classified as CWE-862 (Missing Authorization), meaning the plugin fails to perform adequate authorization checks when a contributor-level user attempts to access or modify resources beyond their permitted scope. An authenticated attacker with contributor privileges can exploit this over the network with low attack complexity and no user interaction required, resulting in unauthorized content or settings modifications. The scope is marked as Changed, indicating the impact extends beyond the vulnerable component itself (GitHub Advisory).

Successful exploitation allows an authenticated contributor to modify website content or settings beyond their intended authorization scope through the Visual Composer Website Builder interface. The primary impact is on integrity (low), with no confidentiality or availability impact. While the individual impact is limited, unauthorized content modification could be leveraged for defacement, injection of malicious content, or privilege escalation within the WordPress site context (GitHub Advisory, Patchstack).

Update the Visual Composer Website Builder plugin to a version newer than 45.15.0, as a patch has been made available per GitHub Advisory GHSA-8pw6-rj96-2r94. As interim measures, administrators should review and audit contributor account permissions, restrict contributor access to only the specific pages or post types they need to manage, and monitor for unexpected content changes. No specific workaround bypassing the need to update has been documented (GitHub Advisory, Patchstack).
