Is this vulnerability remotely exploitable?

It can be, depending on how the application uses Saloon. If fixture names are influenced directly or indirectly by remote input (such as HTTP parameters or user-controlled configuration), a remote attacker may be able to exploit the traversal. If fixture names are entirely internal and never derived from untrusted data, practical exploitability is reduced.

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

The attacker needs a way to influence or control the fixture name used by Saloon's fixture subsystem. This access is often through application-level interfaces—such as APIs that derive fixture identifiers from user input—rather than direct filesystem access. The attack then leverages the application's own permissions on the filesystem.

What is the safest general fix pattern?

The safest pattern is to treat fixture names as opaque identifiers, not raw path fragments. Apply strict input validation (rejecting path separators, `..`, and other unsafe characters), normalize and canonicalize the final path, and enforce that it remains under the intended fixture directory before any file operations. Centralizing these checks in the fixture/storage layer ensures consistent protection.
