CVE-2026-47726 Details
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.
A vulnerability exists in Nebula Mesh versions prior to 0.3.2, where the API endpoint for retrieving the audit log does not properly verify administrative privileges. This endpoint, which is protected by bearer token authentication, can be accessed by any operator API key. The audit log includes sensitive information such as cross-tenant actor names, identification numbers for hosts, certificate authorities, and operators, as well as timestamps and masked IP addresses from rate-limit rejections. This data could allow an operator to analyze server activity, deduce staffing patterns, or pinpoint valuable targets.
Users can update to Nebula Mesh version 0.3.2 or later, where this vulnerability has been patched.
