⚠️ Risk & Real-World Impact
Worst Case
Attackers could compromise administrator accounts, inject malicious JavaScript that steals session cookies or credentials, deface websites, or redirect users to malicious sites.
Likely Case
Attackers create fake forms or links that trick logged-in administrators into executing actions that inject malicious scripts into the site, potentially affecting all visitors.
If Mitigated
With proper CSRF tokens and input validation, the attack would fail as unauthorized requests would be rejected.
🎯 Exploit Status
Exploitation requires tricking an authenticated administrator into clicking a malicious link or visiting a crafted page. CSRF attacks are well-understood and commonly weaponized.
