As a result, any authenticated user with Subscriber level permissions or higher can invoke the emailchef_disconnect AJAX action and delete the plugin\u2019s configuration data, which may break email functionality and cause service disruption.

The EPSS score is not available, and the vulnerability is not listed in the CISA KEV catalog. Attackers would need an authenticated session and Subscriber or higher access, which is relatively common in many WordPress sites. While the vulnerability does not provide direct code execution, deletion of configuration may lead to service disruption. Given the available attack vector, administrators should treat this issue as a priority to prevent service disruption."}}}}, "created": "2026-04-22T11:00:09.088610+00:00", "updated": "2026-04-22T11:43:42.664594+00:00", "vendors": ["hanicker", "hanicker$PRODUCT$emailchef", "wordpress", "wordpress$PRODUCT$wordpress"]}
