CVE-2026-19918: SpaceX Starlink Router Gen 3 gRPC Management get_status access control

A vulnerability has been found in SpaceX Starlink Router Gen 3 2025.11.14.mr64708.3. This affects the function get_status of the component gRPC Management Interface. The manipulation leads to improper access controls. The attack can only be initiated within the local network. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Security readout for executives and security teams

Plain-English summary

A flaw in one identified Starlink Router Gen 3 firmware release may let an unauthenticated device already connected to the local network bypass management-interface access controls. The issue is not described as remotely reachable from the internet, but untrusted or compromised local devices could create risk.

Executive priority

Treat this as a timely network-hardening and firmware-management issue, not an internet-wide emergency. Promptly identify affected routers and reduce local-network trust, especially in shared, guest-accessible, or poorly segmented environments. Escalate if the affected firmware is widespread or management services are reachable by untrusted devices.

Technical view

CVE-2026-19918 affects the gRPC Management Interface get_status function in Starlink Router Gen 3 firmware 2025.11.14.mr64708.3. It is classified under improper privilege and access control weaknesses. CVSS 3.1 is 6.3: adjacent access, low complexity, no privileges or user interaction, with limited confidentiality, integrity, and availability impact.

Likely exposure

Confirmed scope is limited to Starlink Router Gen 3 running 2025.11.14.mr64708.3. An attacker must have local-network adjacency. Exposure is more consequential where guest, unmanaged, or compromised devices share network access with the router management interface. The bundle does not establish whether other firmware versions are affected.

Exploitation context

Technical details or an exploit have reportedly been publicly disclosed, so attempted use is plausible. However, the source bundle provides no evidence of observed attacks, and the CVE is not listed in CISA KEV. Public disclosure should not be interpreted as confirmed active exploitation.

Researcher notes

The assessment rests on a third-party disclosure and CVE metadata. Vendor confirmation, a fixed release, and evidence of attacks are absent from the bundle. Validate exposure non-destructively and avoid assuming that all Gen 3 firmware is vulnerable. Reassess if SpaceX publishes an advisory or the CVE record changes.

Mitigation direction

  • Inventory Starlink Router Gen 3 devices and identify those running firmware 2025.11.14.mr64708.3.
  • Prevent guest and untrusted local devices from reaching router management services where network controls permit.
  • Separate unmanaged or higher-risk devices from trusted administrative network segments.
  • Check SpaceX Starlink guidance for confirmed fixed firmware or vendor-supported mitigation; none is identified in the bundle.

Validation and detection

  • Confirm the router model and installed firmware through approved administrative interfaces.
  • Review network segmentation and access rules protecting the router management interface.
  • Verify guest and untrusted device segments cannot access management services.
  • Monitor authoritative SpaceX guidance and the CVE record for scope or remediation updates.
