WordPress 4.2.x Multiple Vulnerabilities - CVE-2020-28034

WordPress is prone to multiple vulnerabilities including cross-site scripting privilege escalation security bypass Denial of Service and PHP object 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 and launch other attacks to bypass the expected capabilities check to perform otherwise restricted actions and subsequently delete arbitrary files to deny service to legitimate users or to possibly execute arbitrary PHP code within the context of the affected webserver process. WordPress versions 4.2.x ranging from 4.2 and up to (and including) 4.2.28 are vulnerable.
