Likely Case
Attackers create administrator accounts and take over the site, potentially leading to data theft, malware injection, or site compromise.
If Mitigated
With proper access controls and monitoring, exploitation attempts can be detected and blocked before privilege escalation occurs.
🎯 Exploit Status
