Detection Guidance

Check the installed version of the Polylang plugin in your WordPress admin panel under Plugins. If it is version 3.8.5 or earlier, the system is vulnerable. Use commands like 'wp plugin list' in WP-CLI or inspect the plugin files in /wp-content/plugins/polylang/ to verify the version.
