CVE-2025-61916

Credential disclosure via unrestricted artifact URL fetching

Published Jan 5, 2026 · Updated Jan 5, 2026

SSRF in Spinnaker before 2025.1.6 and 2025.2.0 through 2025.2.2 allows local users to fetch internal resources. Clouddriver artifact providers accept user-controlled URLs without restricting destinations, fetch the responses, and pass them to pipeline consumers. Exploitation requires a user-input artifact provider and a consuming system, exposing link-local data, internal APIs, or configured credentials and permitting a service interrupt through an unbounded response.
