This plugin looks at the phishing issue with target=”_blank” vulnerability when the opened page can control the referring page. 
The plugin fixes it by adding a rel=”noopener noreferrer” in the “A” tags where a target=”_blank” is found. It does not 
change the content, it only modifies the “A” tags while the plugin is active. Tested on PHP 5 to PHP 8.
