⚠️ Risk & Real-World Impact
Worst Case
Attackers could inject persistent malicious scripts that steal administrator credentials, deface websites, redirect visitors to malicious sites, or install backdoors for complete site takeover.
Likely Case
Attackers create fake admin panels or forms that trick logged-in administrators into executing actions that inject malicious JavaScript, leading to session hijacking or content manipulation.
If Mitigated
With proper CSRF protections and input validation, the vulnerability would be blocked, preventing the stored XSS chain from being triggered.
🎯 Exploit Status
CSRF exploitation requires social engineering to trick authenticated users. The stored XSS payload persists after successful exploitation.
