⚠️ Risk & Real-World Impact
Worst Case
An attacker gains administrative privileges and accesses all stored passwords, potentially leading to complete system compromise and credential theft across the organization.
Likely Case
A regular user accesses other users' password vaults, exposing sensitive credentials and potentially enabling lateral movement within the network.
If Mitigated
With proper network segmentation and access controls, impact is limited to the TeamPass instance itself, though stored credentials remain at risk.
🎯 Exploit Status
Exploitation requires authenticated access but is technically simple once authenticated. The vulnerability is in authorization checks.
