Is this vulnerability remotely exploitable?

Yes. If the LoginWithV8 interface is exposed over the network, an attacker can send crafted HTTP requests to exploit the path traversal remotely.

What level of access does an attacker need?

The issue is described as allowing unauthorized access, implying that high privileges are not required; access to the affected interface is generally sufficient, though exact requirements depend on deployment and access control configuration.

What is the safest general fix pattern?

The most robust fix is to strictly confine file access to a predefined base directory, normalize and canonicalize all paths, and reject any request whose resolved path falls outside the allowed directory tree.
