Description
WordPress Plugin StageShow is prone to multiple vulnerabilities, including cross-site scripting, cross-site request forgery and open redirect vulnerabilities. Exploiting these issues could 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 perform certain administrative actions and gain unauthorized access to the affected application or to redirect users to arbitrary web sites and conduct phishing attacks. WordPress Plugin StageShow version 5.0.8 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 5.0.9 or latest
