Is this vulnerability remotely exploitable?

Yes. Any user who can remotely authenticate to the OpenEMR application and reach the EtherFax `disposeDocument()` functionality can exploit the bug over HTTP(S), without needing shell access to the server.

Does this require administrative privileges or special roles?

No. The description indicates that any authenticated user, regardless of privilege level, can trigger the arbitrary file read. Low-privileged or standard accounts are sufficient.

What is the safest general fix pattern for this type of bug?

Remove direct path control from the client side, and design the feature around server-side document identifiers that map to vetted paths. All file operations should be constrained to a known base directory, using canonicalization and strict validation to ensure requests cannot escape that boundary.
