CVE-2021-25022

Name of the Vulnerable Software and Affected Versions UpdraftPlus WordPress Backup Plugin versions prior to 1.16.66

Description The issue is related to Reflected Cross-Site Scripting, where the backup timestamp and job id parameters are not properly sanitized and escaped before being outputted back in admin pages. This can lead to security issues.

Recommendations For versions prior to 1.16.66, update to version 1.16.66 or later to resolve the issue. As a temporary workaround, consider restricting access to admin pages to minimize the risk of exploitation. Avoid using the backup timestamp and job id parameters in admin pages until the issue is resolved.
