An app accepts ZIP uploads and extracts into a shared directory. Which vector is most likely to cause a severe compromise?

Large ZIPs causing disk to fill (DoS).

ZIP compressed to tiny size - no issue.

ZIP containing only images - safe.

ZIP with filenames containing ../ causing path traversal (zip-slip).
