Technical details

The weforms_delete_entry_attachments function lacks proper file path validation, allowing path traversal in form entry attachment filenames. An unauthenticated attacker can submit a form with specially crafted attachment file paths; when an administrator routine-deletes the poisoned entry as spam, the vulnerable function deletes arbitrary files on the server. No authentication is required for the initial submission.
