Is this vulnerability remotely exploitable?

Yes, in typical deployments it can be exploited remotely by authenticated users through the lakeFS API or UI, provided the instance is network-accessible and configured with the local block adapter.

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

The attacker must have valid credentials and enough permissions to perform read or write operations via the local block adapter. No direct shell or filesystem access on the host is required; exploitation occurs through the application layer.

What is the safest general fix pattern for this issue?

The safest pattern is to canonicalize paths and enforce strict directory confinement, ensuring that all resolved paths remain under the intended base directory, and to validate object identifiers so they cannot contain traversal sequences or escape their configured namespaces.
