This vulnerability (CVE-2026-62138) is a contributor-level cross-site scripting (XSS) flaw in Visual Composer Website Builder versions up to 45.16.1. It arises from improper neutralization of input during web page generation (CWE-79), enabling an attacker with contributor privileges to inject malicious scripts that could impact confidentiality, integrity, and availability. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with a scope change and partial impact on confidentiality, integrity, and availability.

An attacker with contributor-level access can exploit this XSS vulnerability to execute arbitrary scripts in the context of the affected application, potentially leading to partial compromise of confidentiality, integrity, and availability of the application or user data. However, exploitation requires privileges and user interaction, limiting the attack scope.

No patch or official fix information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit contributor privileges and apply standard XSS mitigations where possible.
