⚠️ Risk & Real-World Impact
Worst Case
Attackers could inject malicious scripts that execute in administrators' browsers, leading to complete site takeover, data theft, or malware distribution to visitors.
Likely Case
Attackers trick administrators into clicking malicious links, resulting in stored XSS payloads being injected into the site, potentially stealing session cookies or defacing content.
If Mitigated
With proper CSRF tokens and input validation, the attack chain is broken, preventing both CSRF and XSS exploitation.
🎯 Exploit Status
Exploitation requires tricking an authenticated administrator into clicking a malicious link; combines CSRF with stored XSS.
