SimplyConvert <= 1.0 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'simplyconvert_hash' Option

The SimplyConvert plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'simplyconvert_hash' option in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
