Name of the Vulnerable Software and Affected Versions: The Event RSVP and Simple Event Management Plugin versions up to, and including, 4.1.0

Description: The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping on user-supplied attributes in the plugin's 'emd mb meta' shortcode. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations: For versions up to, and including, 4.1.0, update to a version that addresses the insufficient input sanitization and output escaping issue in the 'emd mb meta' shortcode to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the 'emd mb meta' shortcode for users with contributor-level access and above until a patch is available.
