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.
