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."}], "lastModified": "2026-09-29T16:50:21.113", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:snipeitapp:snipe-it:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F553C45E-A829-4438-BA02-5FA70B55FB5A", "versionEndExcluding": "8.7.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
