⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, perform actions as authenticated users, deface web interfaces, or redirect users to malicious sites, potentially leading to data theft or unauthorized system access.
Likely Case
Attackers with basic user access inject malicious scripts that execute when other users view affected pages, enabling session hijacking, data theft, or limited privilege escalation within the application.
If Mitigated
With proper input validation and output encoding, the vulnerability is prevented, maintaining normal application functionality without security risks.
🎯 Exploit Status
Requires authenticated user access; stored XSS typically has low exploitation complexity once payload is crafted
