AI Analysis
Technical Summary
CVE-2026-12227 is a Local File Inclusion vulnerability (CWE-98) in the Visual Composer Website Builder WordPress plugin. Versions up to 45.16.0 are affected. The vulnerability arises from improper control of the filename used in an include/require statement, specifically through the 'vcv-template' parameter. This allows unauthenticated remote attackers to include arbitrary files on the server, leading to arbitrary PHP code execution. The CVSS v3.1 base score is 9.8, indicating critical severity with network attack vector, low attack complexity, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
An attacker can remotely include and execute arbitrary PHP files on the affected server without authentication. This can lead to full system compromise, including bypassing access controls, data disclosure, and remote code execution. The vulnerability affects confidentiality, integrity, and availability of the affected system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, restrict access to the vulnerable parameter if possible and monitor for suspicious activity related to file inclusion attempts.
