CVE-2026-37709Network attack vector

Unauthorized file uploads via view-only authorization

Published May 7, 2026 · Updated May 7, 2026

Improper authorization in Snipe-IT before 8.4.1 allows remote authenticated users with view access to upload files to records. The UploadedFilesController store method authorizes POST requests with the view policy instead of the update policy, then persists the supplied file and an audit entry. View permission on an asset, consumable, or another supported object is sufficient; the vendor documents unauthorized file persistence but does not substantiate code execution.
