Is this vulnerability remotely exploitable?

Yes. If ORY Oathkeeper is exposed on the network and has any public or less-restricted routes, an external attacker can remotely exploit the issue by sending crafted HTTP requests with traversal sequences in the path.

Does an attacker need valid credentials or existing access?

Not necessarily. While some deployments may require authentication for all endpoints, the core issue can be exploited wherever there is a difference in privileges between public and protected paths. If any endpoints are publicly accessible based on path rules, an unauthenticated attacker may leverage this vulnerability to reach restricted paths.

What is the safest general fix pattern?

The most robust fix pattern is to ensure that request paths are fully normalized before any access rule evaluation, and that the same canonical path representation is used consistently for both authorization and routing. Additionally, adopt a deny-by-default stance and explicitly protect sensitive endpoints with strict rules.
