HIGHPre-NVD 8.78.7—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.7 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.5%, top 61% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
