CVE-2026-3614 Details
Description
The AcyMailing plugin for WordPress is vulnerable to privilege escalation in all versions From 9.11.0 up to, and including, 10.8.1 due to a missing capability check on the `wp_ajax_acymailing_router` AJAX handler. This makes it possible for authenticated attackers, with Subscriber-level access and above, to access admin-only controllers (including configuration management), enable the autologin feature, create a malicious newsletter subscriber with an injected `cms_id` pointing to any WordPress user, and then use the autologin URL to authenticate as that user, including administrators.
A vulnerability allowing privilege escalation has been identified in the AcyMailing plugin for WordPress, affecting versions 9.11.0 prior to 10.8.1. The issue arises from a missing capability check on the 'wp_ajax_acymailing_router' AJAX handler, which enables authenticated attackers with Subscriber-level access and above to access admin-only controllers, including configuration management. Exploitation of this vulnerability allows the attacker to enable the autologin feature, create a malicious newsletter subscriber with an injected 'cms_id' pointing to any WordPress user, and use the autologin URL to authenticate as that user, potentially including administrators.
Users are advised to update the AcyMailing plugin to version 10.8.2 or a newer patched version.
