AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N
Authenticated uploader (PR:L) and victim must open the URL (UI:R); script runs in-origin crossing to the victim's session (S:C) enabling same-origin read and authenticated actions (C:H/I:H, A:N).

Snipe-IT is an IT asset/license management system. Prior to 8.7.0, the uploaded-files API endpoint GET /api/v1/{object_type}/{id}/files/{file_id} allows an authenticated user with file-management access to upload XML and XSLT attachments and request them with the inline=true parameter. The app/Http/Controllers/Api/UploadedFilesController.php show() path does not apply the safe-inline allowlist used by the equivalent web controller, so the browser can process an attacker-controlled xml-stylesheet reference and execute JavaScript generated by the stylesheet in the Snipe-IT origin. A victim who is authorized to view the object must open the attachment URL, after which the script can read same-origin data and perform authenticated actions with the victim's privileges. This issue is fixed in version 8.7.0.
AnalysisAI
Snipe-IT versions prior to 8.7.0 are affected by stored cross-site scripting in the uploaded-files API: an authenticated user with file-management access can upload an XML attachment carrying an xml-stylesheet reference and then request it through GET /api/v1/{object_type}/{id}/files/{file_id}?inline=true, which the API controller serves with Content-Disposition: inline without the safe-inline allowlist enforced by the equivalent web controller. Because the XML/XSLT is rendered in the Snipe-IT origin, an authorized victim who opens the attachment URL runs attacker-generated JavaScript under their own session, enabling same-origin data reads and authenticated actions with the victim's privileges. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires an authenticated Snipe-IT account with file-management access to upload attachments, plus the ability to reach GET /api/v1/{object_type}/{id}/files/{file_id} with inline=true. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N, base 8.7) describes a network-reachable, low-complexity stored XSS that requires an authenticated uploader (PR:L) and a victim who opens the malicious attachment (UI:R), with a scope change (S:C) because script runs in the Snipe-IT origin under the victim's session. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: upgrade to Snipe-IT 8.7.0 or later, which introduces the config/filesystems.php 'allowed_inline_display' allowlist, makes StorageHelper verify both the extension and the server-detected MIME type, forces non-allowlisted attachments through StorageHelper::downloader() as downloads, and adds 'X-Content-Type-Options: nosniff' with a generic 'application/octet-stream' content type. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Snipe-IT instances and confirm whether any run a version earlier than 8.7.0, then reduce exposure by blocking or tightly restricting GET /api/v1/{object_type}/{id}/files/{file_id}?inline=true at the reverse proxy or WAF, forcing Content-Disposition: attachment and a safe Content-Type for files served through the API, auditing accounts that hold file-management privileges to the minimum necessary, and quarantining or reviewing existing XML/XSLT attachments. …
