Technical details
A Cross-Site Scripting (XSS) vulnerability exists in the SureCart plugin for WordPress (versions <= 4.2.2) due to improper neutralization of input during web page generation (CWE-79). The flaw allows an authenticated attacker with 'Subscriber' privileges to inject malicious HTML or JavaScript payloads. Successful exploitation requires a victim (such as an administrator) to interact with a crafted page or view the injected content. This can lead to unauthorized script execution in the victim's browser session, potentially resulting in data theft or site defacement. The issue is resolved in version 4.2.3.
