Summary
The Royal WordPress Backup & Restore Plugin plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'wpr_pending_template' parameter in all versions up to, and including, 1.0.16 due to insufficient input validation. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick an administrator into performing an action such as clicking on a link.
