      "value": "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."

      "value": "nebula-mesh es un plano de control autohospedado para la red privada virtual de malla Slack Nebula. Antes de la versión 0.3.2, internal/api/audit.go:12 - handleGetAuditLog no realiza ninguna comprobación de administrador. La ruta solo está protegida por autenticación de portador; cualquier clave API de operador devuelve el registro de auditoría completo a través de store.ListAuditEntries (hasta un límite de 1000). Esto incluye nombres de actores entre inquilinos, ID de host/CA/operador, marcas de tiempo de acción y entradas de IP enmascaradas de rechazos por límite de velocidad - superficie suficiente para que un inquilino enumere la actividad del servidor, infiera patrones de personal o identifique objetivos de alto valor. Este problema ha sido parcheado en la versión 0.3.2."
