Cross-namespace TLS-key disclosure via authenticated gRPC impersonation
Published Oct 14, 2026 · Updated Oct 14, 2026
TLS-key disclosure in F5 Networks NGINX Gateway Fabric allows remote authenticated users to read keys via Agent impersonation. The control-plane gRPC connection exposes another namespace's Gateway TLS private keys to an impersonated NGINX Agent; the underlying validation defect is not disclosed in the available evidence. Exploitation requires Gateway CRDs, an authenticated Agent connection, and access to a namespaced service account; the supplied record explicitly excludes data-plane exposure.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
