🔴

Worst Case

Complete compromise of the WordPress site, allowing attackers to install backdoors, steal sensitive data, deface the site, or use it as a platform for further attacks against visitors or connected systems.

Likely Case

Attackers gain administrative access to modify content, install malicious plugins/themes, access user data, and potentially pivot to other systems if the WordPress installation has elevated privileges.

🟢

If Mitigated

Limited impact if proper network segmentation, least privilege principles, and strong authentication controls are in place, though the WordPress site itself would still be compromised.
