What the vulnerability does
01Description
The Voyage Plus plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'class' attribute of the 'post-content' shortcode in all versions up to, and including, 1.0.6 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
