Name of the Vulnerable Software and Affected Versions Backup and Staging by WP Time Capsule WordPress plugin versions prior to 1.22.7

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

Recommendations For versions prior to 1.22.7, update to version 1.22.7 or later to resolve the issue. As a temporary workaround, consider restricting access to the admin page where the error parameter is outputted to minimize the risk of exploitation.
