⚠️ Risk & Real-World Impact
Worst Case
Attackers could inject persistent malicious scripts that steal administrator credentials, hijack user sessions, deface websites, or redirect visitors to malicious sites.
Likely Case
Attackers create fake admin actions to inject malicious JavaScript into website content, affecting visitors who view compromised pages.
If Mitigated
With proper CSRF protections and input validation, the attack surface is significantly reduced, though underlying code flaws may remain.
🎯 Exploit Status
Exploitation requires tricking authenticated users into performing actions, but the stored XSS payload persists after initial compromise.
