⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, hijack user sessions, deface the application, or redirect users to malicious sites, potentially leading to full system compromise.
Likely Case
Session hijacking, credential theft, or data exfiltration from authenticated users accessing the vulnerable dataset upload interface.
If Mitigated
Limited impact if proper input validation and output encoding are implemented, though some functionality disruption may occur.
🎯 Exploit Status
Exploitation requires sending crafted HTTP requests to the vulnerable endpoint; no authentication bypass needed if user has upload permissions.

- Disable dataset upload functionality if not required
🔍 How to Verify
Check if Vulnerable:
Test dataset upload functionality with XSS payloads; check if payloads execute in browserCheck Version:
clearml-server --version or check ClearML web interface version infoVerify Fix Applied:
Attempt to upload dataset with XSS payloads; verify payloads are properly sanitized and don't execute📡 Detection & Monitoring
