The Shield Security plugin for WordPress is vulnerable to stored Cross-Site Scripting in versions up to, and including, 17.0.17 via the \'User-Agent\' header. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
