Name of the Vulnerable Software and Affected Versions All 404 Redirect to Homepage WordPress plugin versions prior to 1.21

Description The issue concerns an authenticated reflected Cross-Site Scripting (XSS) problem. It occurs because user input for the tab parameter on the settings page is not properly sanitized before being output in an attribute. This allows for malicious script execution.

Recommendations For versions prior to 1.21, update to version 1.21 or later to resolve the issue. As a temporary workaround, consider restricting access to the settings page to minimize the risk of exploitation. Avoid using the tab parameter in the affected settings page until the issue is resolved.
