CVE-2026-47722
Published:July 23, 2026
Updated:August 04, 2026
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.
