The Cincopa video and media plug-in plugin for WordPress is vulnerable to Stored Cross-Site Scripting via cincopa Shortcode in Post Comments in all versions up to, and including, 1.163 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. Exploitation is possible because the plugin processes the [cincopa] shortcode via a comment_text filter hook, allowing unauthenticated visitors who can post comments to supply a malicious shortcode argument that persists in the database.
