Is this vulnerability remotely exploitable, or does it require local access?

Exploitation is typically remote in nature: an attacker interacts with Backstage over the network. However, they must have sufficient permissions within Backstage to create or execute Scaffolder templates or otherwise control inputs used by file operations.

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

The attacker must be able to: - Create or modify templates that invoke vulnerable actions (such as logging, deleting, or extracting files), or - Trigger existing templates that consume attacker-controlled archives or file paths. In most deployments, this corresponds to a developer or system-integrator role, not an unauthenticated external user.

What is the safest general fix pattern for this class of vulnerability?

The most robust fix is to enforce strict directory boundaries by resolving paths and confirming they stay within a designated workspace, combined with explicit handling or outright rejection of symlinks in any attacker-influenced location. This pattern should be applied consistently across all file operations—reads, writes, deletes, and archive extraction.
