The WP Meta SEO plugin for WordPress is susceptible to Stored Cross-Site Scripting (XSS) vulnerabilities that arise from improper handling of the 'Referer' header. This flaw, present in all versions up to and including 4.5.12, allows unauthenticated attackers to inject malicious scripts into web pages.
