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

The qrscp application's C-STORE handler uses a specific instance from attacker-supplied DICOM datasets directly in os.path.join() without sanitization, allowing file writes to arbitrary paths.
