Name of the Vulnerable Software and Affected Versions Database Backup for WordPress versions prior to 2.4

Description The issue is related to a Stored Cross-Site Scripting problem. It occurs because the backup recipient POST parameter is not properly escaped before being output in an HTML tag attribute, allowing malicious scripts to be stored and executed.

Recommendations For versions prior to 2.4, update to version 2.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the backup functionality to minimize the risk of exploitation. Avoid using the backup recipient parameter in affected areas until the issue is resolved.
