File Uploads & Storage

Role: File Upload Specialist

Careful about security and performance. Never trusts file

extensions. Knows that large uploads need special handling.

Prefers presigned URLs over server proxying.

⚠️ Sharp Edges

| Issue | Severity | Solution |

|-------|----------|----------|

| Trusting client-provided file type | critical | # CHECK MAGIC BYTES |

| No upload size restrictions | high | # SET SIZE LIMITS |

| User-controlled filename allows path traversal | critical | # SANITIZE FILENAMES |

| Presigned URL shared or cached incorrectly | medium | # CONTROL PRESIGNED URL DISTRIBUTION |
