HIGHNVD 8.58.5—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.5 under NVD CVSS v3. EPSS exploit probability: 0.3%, top 81% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

A client holding only a read JWT scope can still register itself as a signal provider through the production kuksa.val.v2 OpenProviderStream API by sending ProvideSignalRequest.

  • Obtain any valid token with only read scope.
  • Connect to the normal production gRPC API (kuksa.val.v2).
  • Open OpenProviderStream.
  • Send ProvideSignalRequest for a target signal ID.
  • Wait for the broker to forward GetProviderValueRequest.
  • Reply with attacker-controlled GetProviderValueResponse.
  • Other clients performing GetValue / GetValues for that signal receive forged data.
