Who should care

Administrators and users of WordPress sites using the WP TripAdvisor Review Slider plugin, especially those with administrator-level access, should be aware of this vulnerability and take immediate action to protect their sites. This includes updating the plugin to the latest version, limiting administrator-level access, and monitoring database activity for suspicious queries.
