OpenProject is open-source, web-based project management software. Prior to 17.6.0, PATCH /api/v3/work packages/{id} accepted links.fileLinks and allowed authenticated users with edit work packages but without manage file links to resolve Storages::FileLink records by raw id, detach or hard-delete existing FileLinks, and re-parent FileLinks from other projects to an attacker-controlled work package, exposing origin filename, origin id, and MIME type metadata. This issue is fixed in 17.6.0.
