Summary

Snipe-IT: Chained Information Disclosure and IDOR Leads to Full EULA File Takeover

Details

Impact

An attacker can completely bypass file-name randomization security and without authorization download confidential, signed EULA files belonging to any other user across the application.

Steps to Reproduce:

Log in as a restricted user.
Send a GET request to /api/v1/users/{target_id}/eulas (where target_id belongs to a restricted/denied user).
Observe the response leaks the secret EULA filename (e.g., eula-xxx.pdf).
Attempt to access this file via the main route: GET /stored-eula-file/{filename} (This will correctly return 403 Forbidden).
Now, access the file via the vulnerable profile route: GET /account/stored-eula-file/{filename}.
Observe that the server returns a 200 OK and successfully downloads the target user's secret EULA file.

CVE-2026-55694 (GCVE-0-2026-55694)

Vulnerability from cvelistv5 – Published: 2026-08-19 18:28 – Updated: 2026-08-19 19:23

Title

Snipe-IT: Chained Information Disclosure and IDOR Leads to Full EULA File Takeover

Summary

Snipe-IT is an IT asset/license management system. Prior to 8.6.3, a restricted user can request /api/v1/users/{target_id}/eulas to obtain another user's randomized EULA filename and then download the signed file through /account/stored-eula-file/{filename}. The primary /stored-eula-file/{filename} route correctly denies access, but app/Http/Controllers/ProfileController.php and app/Http/Controllers/Api/UsersController.php do not consistently enforce ownership and target-user authorization. This issue is fixed in version 8.6.3.

Severity

7.1 (High)
