Description
WordPress Plugin SlickQuiz is prone to multiple vulnerabilities, including cross-site scripting and SQL injection 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, or to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database. WordPress Plugin SlickQuiz version 1.3.7.1 is vulnerable; prior versions may also be affected.
Remediation
Disable the plugin until a fix is available
