Description
The Contact Form by Supsystic plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to 1.10.0. This is due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
