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.
Fix
Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
