Add to wp-config.php: define('FORCE_SSL_ADMIN', true);
Add to .htaccess: Header set X-Frame-Options "DENY"
Header set Content-Security-Policy "default-src 'self'"
Install security plugin like Wordfence for additional CSRF protection
Disable Plugin Temporarily
allDeactivate Language Field plugin until patched version is available
wp plugin deactivate language-field
Or via WordPress admin: Plugins → Installed Plugins → Language Field → Deactivate
🧯 If You Can't Patch
