A popular tool used with WordPress, called the Newsletters plugin, has a security issue that affects all versions up to 4.10. This means that anyone without proper credentials can access and run any files they want on the server. This can lead to bypassing security measures, getting confidential information, or even running code through seemingly harmless files like images.
