- CVE-2026-95588, 1 Oct 2026
- Unauthenticated Arbitrary File Deletion in AcyMailing SMTP Newsletter <= 11.0.5 versions. CVE record
- CVE-2026-77807, 11 Sep 2026
- The AcyMailing - An Ultimate Newsletter Plugin and Marketing Automation Solution for WordPress plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 11.0.4 via the `user[name]` Parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. Exploitation requires "Embed images" option in AcyMailing configuration being enabled. CVE record
- CVE-2026-15426, 11 Aug 2026
- 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. CVE record
- CVE-2026-12170, 9 Jul 2026
- The AcyMailing - An Ultimate Newsletter Plugin and Marketing Automation Solution for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'alignment' attribute in all versions up to, and including, 10.10.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE record
- CVE-2026-5200, 20 May 2026
- The AcyMailing - An Ultimate Newsletter Plugin and Marketing Automation Solution for WordPress plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 10.8.2. 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 modify privileged AcyMailing configuration, export subscriber secret keys, and chain these actions into administrator account takeover when a target administrator email address is known. CVE record
- CVE-2026-3614, 16 Apr 2026
- 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. CVE record
- CVE-2024-7384, 22 Aug 2024
- The AcyMailing - An Ultimate Newsletter Plugin and Marketing Automation Solution for WordPress plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the acym_extractArchive function in all versions up to, and including, 9.7.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
