Description
WordPress Plugin Welcart e-Commerce is prone to multiple vulnerabilities, including cross-site scripting, privilege escalation and PHP object injection vulnerabilities. Exploiting these issues may allow an attacker to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site, allowing the attacker to steal cookie-based authentication credentials and launch other attacks, to bypass the expected capabilities check and perform otherwise restricted actions or to execute arbitrary PHP code within the context of the affected webserver process. WordPress Plugin Welcart e-Commerce version 1.8.2 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 1.8.3 or latest
