Name of the Vulnerable Software and Affected Versions UpdraftPlus WordPress Backup Plugin versions prior to 1.16.69

Description The issue is related to a Reflected Cross-Site Scripting problem. It occurs because the updraft restore parameter is not properly sanitised and escaped before being outputted back in the Restore page. This allows for potential malicious script injection.

Recommendations For versions prior to 1.16.69, update to version 1.16.69 or later to resolve the issue. As a temporary workaround, consider restricting access to the Restore page until the update is applied. Avoid using the updraft restore parameter in the affected Restore page until the issue is resolved.
