Is this vulnerability remotely exploitable?

It can be remotely exploitable if OneFlow-based services expose endpoints, notebooks, or job submission interfaces where remote users can control the arguments passed to flow.arange().

What level of access is required to exploit this issue?

An attacker generally needs the ability to submit crafted inputs to an API, script, or configuration that ultimately calls flow.arange(). No special system-level privileges are required beyond that application-level access.

What is the safest general fix pattern?

Introduce strict input validation and bounding logic before every use of flow.arange(), ensuring type correctness, reasonable range sizes, and rejecting pathological or malformed values rather than letting them reach the underlying computation.
