Summary
Signal K Server, an open-source marine data platform, is affected, and attackers can abuse its App Store icon feature to make the server fetch internal or cloud-hosted addresses it should not reach. Those fetched image responses can then be stored and displayed through the admin interface, potentially exposing internal network data.

Signal K Server from 2.28.0-beta.2 before 2.34.0 contains a server-side request forgery vulnerability in the App Store icon fetcher that trusts absolute signalk.appIcon URLs. Attackers publishing npm packages with Signal K keywords can make servers request loopback, vessel network, or cloud metadata endpoints, storing image-typed responses served back via the admin UI.
