CVE-2026-23693
CriticalSummary
Wtyczka ElementsKit Elementor Addons w wersjach przed 3.7.9 udostępnia punkt końcowy REST /wp-json/elementskit/v1/widget/mailchimp/subscribe bez wymogu uwierzytelnienia. Punkt końcowy akceptuje dane uwierzytelniające API Mailchimp dostarczone przez klienta i niewystarczająco waliduje niektóre parametry, co może prowadzić do nieautoryzowanych działań.
Risk Assessment
Nieautoryzowany atakujący może wykorzystać ten punkt końcowy jako otwarty proxy do Mailchimp, co może prowadzić do nieautoryzowanych wywołań API, manipulacji danymi subskrypcyjnymi oraz wyczerpywania limitów API, co zagraża stabilności i bezpieczeństwu strony WordPress.
Recommendation
Zaleca się aktualizację wtyczki ElementsKit do wersji 3.7.9 lub nowszej oraz wdrożenie odpowiednich mechanizmów uwierzytelniania dla punktów końcowych REST, aby zabezpieczyć dostęp do API Mailchimp.

Original NVD description (English source)
ElementsKit Elementor Addons – Advanced Widgets & Templates Addons for Elementor (elementskit-lite) WordPress plugin versions prior to 3.7.9 expose the REST endpoint /wp-json/elementskit/v1/widget/mailchimp/subscribe without authentication. The endpoint accepts client-supplied Mailchimp API credentials and insufficiently validates certain parameters, including the list parameter, when constructing upstream Mailchimp API requests. An unauthenticated attacker can abuse the endpoint as an open proxy to Mailchimp, potentially triggering unauthorized API calls, manipulating subscription data, exhausting API quotas, or causing resource consumption on the affected WordPress site.
