⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, hijack user accounts, perform actions as authenticated users, or redirect to malicious sites, potentially leading to full system compromise.
Likely Case
Attackers steal session tokens to impersonate users, access sensitive project data, or modify application content.
If Mitigated
With proper input validation and output encoding, the attack would fail to execute JavaScript, limiting impact to benign title display issues.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once authenticated.
