Is this vulnerability remotely exploitable over the internet?

Yes, in typical deployments it can be exploited remotely by any attacker who can authenticate and provide or modify URLs in Spinnaker pipeline or artifact configuration. The actual network requests, however, originate from the internal Spinnaker infrastructure, not from the attacker's machine.

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

The attacker usually needs sufficient permissions to create or edit pipelines, artifacts, or expressions that reference URLs (for example, a compromised user account or API token with those privileges). Public unauthenticated exploitation is unlikely unless such configuration interfaces are exposed without access control.

What is the safest general fix pattern for this issue?

The safest pattern is to decouple security decisions from generic Java URL parsing, instead enforcing strict, explicit validation and allowlists for destination hosts and networks, combined with network-layer egress controls so that components handling user-supplied URLs cannot reach sensitive internal services.
