Description
The HTML Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via form submission field names in all versions up to, and including, 1.7.1 due to insufficient input sanitization of submitted field keys, which were only passed through strip_tags(), and their use as column identifiers in the submissions screen's Screen Options, where they are output unescaped. This makes it possible for unauthenticated attackers to inject arbitrary web scripts through crafted field names that will execute whenever an administrator views the form's submissions list.
