No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The Workreap WordPress theme before 2.2.2 AJAX actions workreap_award_temp_file_uploader and workreap_temp_file_uploader did not perform nonce checks, or validate that the request is from a valid user in any other way. The endpoints allowed for uploading arbitrary files to the uploads/workreap-temp directory. Uploaded files were neither sanitized nor validated, allowing an unauthenticated visitor to upload executable code such as php scripts.
