It's not Read (no retrieval), Execute (no external command execution with variable effects), Destructive (reversible via deletion), or Financial (no monetary transaction). Severity is medium because while uploads are typically low-risk, they occur on a blockchain protocol with potential for spam, phishing content, or abuse.
