⚠️ Risk & Real-World Impact
Worst Case
Attackers could inject malicious JavaScript that steals administrator credentials, defaces websites, redirects users to malicious sites, or installs backdoors when administrators view affected pages.
Likely Case
Attackers create fake requests that trick logged-in administrators into unknowingly adding malicious scripts to the site, which then execute in visitors' browsers.
If Mitigated
With proper CSRF tokens and input validation, the attack chain is broken and no malicious actions can be performed.
🎯 Exploit Status
Exploitation requires social engineering to trick authenticated users into clicking malicious links. The CSRF leads to stored XSS payload injection.
