⚠️ Risk & Real-World Impact
Worst Case
Attackers could hijack administrator sessions, deface websites, inject malware, steal sensitive data, or create backdoor administrator accounts for persistent access.
Likely Case
Attackers inject malicious JavaScript that steals session cookies or performs unauthorized actions when administrators view compromised pages/posts.
If Mitigated
With proper CSRF tokens and input validation, the attack chain would be broken at the initial CSRF stage, preventing XSS injection.
🎯 Exploit Status
Exploitation requires social engineering to trick authenticated users into clicking malicious links. The CSRF leads to stored XSS, making the attack persistent.
