Access violation vulnerability in Popup – MailChimp, GetResponse and ActiveCampaign Intergrations 3.2.6

The plugin called “Popup – MailChimp, GetResponse and ActiveCampaign Intergrations” for WordPress is at risk for losing important information without proper authorization. This is because it lacks a security measure for the ‘upc_delete_db_data’ action, which is used in all versions up to 3.2.6. This can be exploited by hackers who are not logged in, allowing them to delete the plugin’s database information.
