Background for this topic.
WordPress is an open-source content management system (CMS) used to publish and manage websites. A site typically combines WordPress core with independently developed plugins and themes, which extend functionality but create a diverse and changing software supply chain. Its security therefore depends not only on the core software, but also on the quality, maintenance, and configuration of those extensions.
Security-relevant issues include exploitable vulnerabilities in core, plugins, or themes; weak or reused administrator credentials; and exposed or poorly configured administrative and API interfaces. Attackers may use these paths to alter content, install malicious code, or access site data. Administrators should track advisories and affected versions, apply updates through a controlled process, remove unsupported extensions, enforce strong authentication and least privilege, and keep protected, tested backups. Monitoring and log review help identify unauthorized changes and support recovery when compromise is suspected.
