Name of the Vulnerable Software and Affected Versions Shield Security plugin for WordPress versions up to, and including, 17.0.17

Recommendations For Shield Security plugin for WordPress versions up to, and including, 17.0.17, update to a version later than 17.0.17 to resolve the issue. As a temporary workaround, consider restricting access to the 'theme-plugin-file' AJAX action to minimize the risk of exploitation.
