📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker could access, modify, or delete sensitive files belonging to other users, potentially leading to data breaches, compliance violations, or business disruption.
Likely Case
Authenticated users inadvertently or intentionally accessing files they shouldn't have permission to view or modify, leading to data exposure or integrity issues.
If Mitigated
With proper network segmentation and least-privilege access controls, impact would be limited to authorized users within the same security zone.
🎯 Exploit Status
Exploitation requires authenticated access but minimal technical skill once authenticated.
