Description
WordPress Plugin iThemes Security (formerly Better WP Security) is prone to multiple vulnerabilities, including cross-site scripting and information disclosure vulnerabilities. An attacker may leverage these issues 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 launch other attacks or to obtain sensitive information that may help in launching further attacks. WordPress Plugin iThemes Security (formerly Better WP Security) version 3.6.3 is vulnerable; other versions may also be affected.
