The PostmarkApp Email Integrator plugin for WordPress has a security issue that allows unauthorized access. This happens because the plugin does not have a check in place to prevent certain users from performing actions. This means that attackers who are logged in and have at least Subscriber-level access can perform actions they should not be able to.
