Executive Summary

The Royal WordPress Backup & Restore Plugin is vulnerable to Reflected Cross-Site Scripting (XSS) via the 'wpr_pending_template' parameter in all versions up to and including 1.0.16. This vulnerability arises due to insufficient input validation, allowing unauthenticated attackers to inject arbitrary web scripts.

These injected scripts execute if an administrator is tricked into performing an action, such as clicking on a malicious link.

Impact Analysis

This vulnerability can allow attackers to execute arbitrary scripts in the context of an administrator's browser session. This can lead to unauthorized actions being performed with administrator privileges.

  • Potential impacts include theft of sensitive information, session hijacking, or manipulation of the WordPress site.
  • Because the attack requires tricking an administrator into clicking a link, it relies on social engineering.
