MelaPress Login Security <= 1.3.0 is vulnerable to Remote File Inclusion vulnerability

The MelaPress Login Security plugin for WordPress is vulnerable to Remote File Inclusion in all versions up to, and including, 1.3.0 via the 'tab' parameter. This makes it possible for authenticated attackers, with Administrator-level access and above, to include and execute arbitrary files hosted on remote servers, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution. This requires the site to have the allow_url_include setting to be enabled.
