This vulnerability in voidcoders WPBakery Visual Composer WHMCS Elements (<= 1.0.4.3) allows stored cross-site scripting due to improper input neutralization during web page generation. An attacker with low privileges and requiring user interaction can exploit this to inject malicious scripts, potentially impacting confidentiality, integrity, and availability of the affected system. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with a scope change and low impact on confidentiality, integrity, and availability.

Successful exploitation can lead to stored XSS attacks, which may allow attackers to execute arbitrary scripts in the context of the affected web application. This can result in information disclosure, session hijacking, or other impacts on confidentiality, integrity, and availability as indicated by the CVSS vector. However, exploitation requires user interaction and some privileges, limiting the ease of attack. No known active exploits have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit privileges of users who can input data into the affected plugin and consider disabling or restricting the plugin if feasible. Monitor vendor channels for updates and apply patches promptly once released.
