Oct 13, 2026AcyMailing: Stored Cross-Site ScriptingCVE-2026-102562 · WordPress plugins & themes · reported by WordfenceHigh 7.2
The AcyMailing plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the customField[] parameter of the public frontusers::subscribe endpoint in versions up to, and including, 11.1.0. This is due to insufficient input sanitization and output escaping in the acym_cleanVar() sanitizer, whose HTML-tag stripper only matches complete tags (requiring a closing '>'), together with SubscriberInsertion::replaceUserInformation() and the archive view template, which substitute the stored subscriber field value into the mail body and emit it without HTML encoding. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses the online-archive URL for the poisoned subscriber, including administrators who click the plugin-generated link in the Subscribers → History screen.

Aug 11, 2026AcyMailing – An Ultimate Newsletter Plugin and Marketing Automation Solution for: Authorization bypassCVE-2026-15426 · WordPress plugins & themes · reported by WordfenceHigh 8.8
The AcyMailing – An Ultimate Newsletter Plugin and Marketing Automation Solution for WordPress plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 10.11.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to overwrite the BCC field of the acy_notification_cms notification template, causing subsequent WordPress password-reset emails — including those targeting administrator accounts — to be silently copied to an attacker-controlled address, enabling account takeover via the captured reset link. Successful exploitation requires the site administrator to have enabled the "Send website emails with AcyMailing" option, which routes WordPress core notification emails through AcyMailing's templating system.

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.
