# Vendor Homepage: https://snipeitapp.com
# Software Link: https://github.com/grokability/snipe-it
# Version: <= 8.0.4

# CVE: CVE-2025-47226

# Vulnerability Description:
Snipe-IT <= 8.0.4 contains an Insecure Direct Object Reference (IDOR) vulnerability in the
`/locations/<id>/printassigned` endpoint. This flaw allows an authenticated user from one
department to gain access to asset assignment data belonging to other departments by modifying
the `location_id` in the URL.

# Steps to Reproduce:
1. Authenticate with a low-privileged account assigned to `location_id = 2`.
2. Access the print preview page:
   https://<target>/locations/2/printassigned
3. Modify the URL to:
   https://<target>/locations/1/printassigned
4. The application will disclose inventory/assignment information for location ID 1,
   even if the user should not have access.

# Impact:
- Unauthorized access to internal asset and inventory information.
- Potential for lateral data exposure between departments in the same organization.
- Disclosure of asset IDs, assignees, and location metadata.

# Mitigation:
Update to **Snipe-IT v8.1.0** or higher where access control validation has been corrected.
