Is this vulnerability remotely exploitable?

It can be, depending on how the application accepts DICOM input. If an attacker can upload or otherwise supply a DICOMDIR file over the network and the server processes it with pydicom FileSet operations, then exploitation can occur remotely within the context of that service.

What level of access does an attacker need to exploit this issue?

The attacker must be able to influence or control the DICOMDIR used by the application. This commonly means having the ability to upload or import DICOM media, or to cause the application to open attacker-provided DICOMDIR files from removable media or network locations.

What is the safest general fix pattern for developers?

The safest pattern is to treat all paths derived from DICOMDIR ReferencedFileID values as untrusted and enforce a strong directory containment check. Normalize the path, ensure it is anchored under a predefined File-set root, and reject or sanitize any entry that does not meet this constraint before performing file I/O.
