The Newsletter plugin for WordPress, which allows users to send emails, has a security issue. This problem, called IP Address Spoofing, affects all versions up to 8.2.0. It happens because the plugin does not properly check IP addresses. This means that unauthorized people can fake their IP address and get around the blocklist.
