Technical details
The plugin fails to validate upload field metadata in POST requests when processing draft form submissions, allowing poisoned metadata to be stored. When a subsequent draft references the compromised draft via previous_draft_id, the plugin uses the unvalidated metadata to delete arbitrary files in wp-content/uploads/ without authentication. An unauthenticated attacker can exploit this to remove non-PHP files from the server.
