Description

WordPress is prone to multiple vulnerabilities, including cross-site scripting and directory traversal 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, or to obtain sensitive information that could aid in further attacks. WordPress version 4.6 is vulnerable.

Remediation

Update to WordPress version 4.6.1 or latest
