Description
WordPress is prone to multiple vulnerabilities, including cross-site scripting, SQL injection 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 compromise the application, access or modify data or exploit vulnerabilities in the underlying database or to redirect users to arbitrary web sites and conduct phishing attacks. WordPress version 2.2.1 is vulnerable.
Remediation
Update to WordPress version 2.2.2 or latest
