Description

nebula-mesh is a self-hosted control plane for Slack Nebula mesh virtual private network. Prior to version 0.3.2, internal/api/audit.go:12 — handleGetAuditLog does no admin check. The route is bearer-auth gated only; any operator API key returns the full audit log via store.ListAuditEntries (up to limit=1000). This includes cross-tenant actor names, host/CA/operator IDs, action timestamps, and masked-IP entries from rate-limit refusals — enough surface for a tenant to enumerate the server's activity, infer staffing patterns, or identify high-value targets. This issue has been patched in version 0.3.2.
