nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN. Prior to version 0.7.1, revocation is the only in-band mechanism that isolates a compromised\/offboarded host from a Nebula mesh. Because the blocklist never reaches any peer’s config.yml, a Blocked host retains full overlay reachability to every peer under its CA (and internal services on the mesh) for up to 30d (agent) \/ 365d (mobile). An attacker who exfiltrates host.key+host.crt can run stock slackhq\/nebula directly, ignore the agent’s 403\/410 poll responses, and stay connected after the operator revokes the host. Operator-visible state (UI shows blocked, audit log records it) is misleading. This issue has been patched in version 0.7.1.<\/p>\n","protected":false},"excerpt":{"rendered":"
