Is this vulnerability remotely exploitable?

Yes. If Cassandra Web is accessible over the network, an unauthenticated remote user can exploit the directory traversal by sending crafted HTTP requests.

Does exploitation require valid credentials or login access?

No. The described issue affects unauthenticated endpoints, so attackers do not need valid credentials to attempt exploitation.

What is the safest general fix pattern for developers?

Constrain all file access operations to a fixed, canonical base directory, normalize incoming paths, and reject any request that resolves outside that directory. Prefer mapping user input to predefined identifiers instead of accepting raw paths.
