Likely Case
Attackers would typically inject scripts to steal session cookies or admin credentials, potentially gaining full control of the WordPress site.
If Mitigated
With proper CSRF protections and input validation, the attack would fail at the initial CSRF stage, preventing XSS payload injection entirely.
