📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, perform session hijacking, install malware on user systems, or pivot to internal network attacks.
Likely Case
Session theft for low-privileged users, data exfiltration from user browsers, or limited account compromise.
If Mitigated
With proper input validation and output encoding, impact is limited to script execution in isolated browser contexts.
🎯 Exploit Status
Vulnerability is described as 'difficult to exploit' and requires low-privileged access
