Is this vulnerability remotely exploitable over the network?

Yes. Any attacker who can reach the D-Tale instance over the network and send requests to the /save-column-filter endpoint may be able to attempt exploitation, especially when the service is exposed to the public internet.

Does an attacker need authenticated access or local system access?

The primary requirement is network access to the vulnerable endpoint. Whether authentication is required depends on how D-Tale is deployed; some setups might expose it without strong authentication, increasing the risk. Local OS-level access is not necessary.

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

The safest pattern is to entirely avoid treating user-supplied filter definitions as code. Implement a strictly defined, declarative filter model that is parsed using safe, deterministic parsers and never passed to generic evaluation or execution mechanisms. Combine this with strong input validation and clear separation between data and executable logic.
