⚠️ Risk & Real-World Impact
Worst Case
Attackers could access configuration files, database credentials, or other sensitive system information, potentially leading to full system compromise or data exfiltration.
Likely Case
Attackers with valid credentials access sensitive configuration files containing database credentials or system information.
If Mitigated
With proper access controls and network segmentation, impact is limited to the application's data scope.
🎯 Exploit Status
Requires authenticated access. Path traversal vulnerabilities are typically straightforward to exploit once discovered.
