  • Alternate Plugins: If an immediate update is not feasible, consider temporarily disabling the plugin or using alternative currency switcher plugins that do not have known vulnerabilities.
  • Stay Updated: Regularly check for updates on all plugins installed on your site and apply them as soon as they are available to prevent potential vulnerabilities.
