CVE-2026-47722
nebula-mesh is a self-hosted control plane for Slack Nebula mesh virtual private network.
Overview
CVE-2026-47722 is a known-severity vulnerability. It was published on July 23, 2026.
Technical description
nebula-mesh is a self-hosted control plane for Slack Nebula mesh virtual private network. Prior to version 0.3.2, `internal/configgen/generator.go:86,108,119` interpolates the operator-supplied `ListenHost` and `TunDevice` fields raw into a `text/template` that produces the agent's `config.yml`. `internal/web/advanced.go:20-35` accepts both with only `strings.TrimSpace` — no character or shape validation. Version 0.3.2 fixes the issue.
