# Pattern: Secure File Upload Pipeline
|
|
|
|
Status: seed
|
|
Readiness target: RL3 production
|
|
Primary owners: product repos, artifact-store, NetKingdom
|
|
Genesis family: Application/API security
|
|
|
|
## Problem
|
|
|
|
User-supplied files can carry malware, parser attacks, data leakage, and
|
|
unsafe object-storage exposure.
|
|
|
|
## Context
|
|
|
|
Use this pattern for tenant file uploads, artifact ingestion, document
|
|
processing, media upload, and user-controlled object storage paths.
|
|
|
|
## Forces
|
|
|
|
- Users need convenient uploads.
|
|
- Uploaded files should not be trusted until processed.
|
|
- Scanning, classification, and transformation may be asynchronous.
|
|
- Object access must remain tenant and authorization scoped.
|
|
|
|
## Solution
|
|
|
|
Route uploads through a controlled pipeline: accept to quarantine,
|
|
record metadata, scan/classify, transform if needed, promote to trusted
|
|
storage, and serve through authorized access paths.
|
|
|
|
## Verification
|
|
|
|
- Raw uploads land in quarantine or untrusted storage.
|
|
- Scanning and classification results are recorded before promotion.
|
|
- Access to uploaded objects uses tenant and object-level authorization.
|
|
- Malicious or unsupported files fail safely.
|
|
