Name of the Vulnerable Software and Affected Versions Scheduled Announcements Widget WordPress plugin versions prior to 1.0

Description The issue arises from the lack of validation and escaping of some shortcode attributes in the Scheduled Announcements Widget WordPress plugin. This could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks by embedding malicious code in a page or post where the shortcode is used.

Recommendations For versions prior to 1.0, update to version 1.0 or later to resolve the issue. As a temporary workaround, consider restricting the use of the Scheduled Announcements Widget to minimize the risk of exploitation. Additionally, limit the contributor role and above to trusted users to reduce the potential attack surface.
