From 2b48b0a459ee5379805cdb0eb69b978f5ed820a9 Mon Sep 17 00:00:00 2001 From: rcourtman Date: Thu, 18 Dec 2025 20:58:30 +0000 Subject: [PATCH] feat: add --kube-include-all-deployments flag for Kubernetes agent Adds IncludeAllDeployments option to show all deployments, not just problem ones (where replicas don't match desired). This provides parity with the existing --kube-include-all-pods flag. - Add IncludeAllDeployments to kubernetesagent.Config - Add --kube-include-all-deployments flag and PULSE_KUBE_INCLUDE_ALL_DEPLOYMENTS env var - Update collectDeployments to respect the new flag - Add test for IncludeAllDeployments functionality - Update UNIFIED_AGENT.md documentation Addresses feedback from PR #855 --- README.md | 6 +- SECURITY.md | 66 +-- cmd/pulse-agent/main.go | 29 +- cmd/pulse-sensor-proxy/README.md | 12 +- deploy/helm/pulse/README.md | 4 +- deploy/helm/pulse/values.yaml | 2 + docs/AI.md | 133 ++---- docs/API.md | 61 ++- docs/AUTO_UPDATE.md | 24 +- docs/CONFIGURATION.md | 24 +- docs/DEPLOYMENT_MODELS.md | 62 +++ docs/DOCKER.md | 4 +- docs/DOCS_AUDIT_V5.md | 317 ++++++++++++++ docs/FAQ.md | 42 +- docs/INSTALL.md | 41 +- docs/KUBERNETES.md | 23 +- docs/MAIL_GATEWAY.md | 26 +- docs/METRICS_HISTORY.md | 119 +++--- docs/MIGRATION.md | 38 +- docs/PROXY_CONTROL_PLANE.md | 3 +- docs/PULSE_PRO_IMPLEMENTATION.md | 401 ++++++++++++++++++ docs/README.md | 8 +- docs/RELEASE_NOTES.md | 130 +----- docs/SECURITY_AUDIT_2025-12-18.md | 375 ++++++++++++++++ docs/SECURITY_CHANGELOG.md | 7 +- docs/TEMPERATURE_MONITORING.md | 133 +++--- docs/TROUBLESHOOTING.md | 23 +- docs/UNIFIED_AGENT.md | 1 + docs/UPGRADE_v5.md | 66 +++ docs/VM_DISK_MONITORING.md | 3 +- docs/WEBHOOKS.md | 2 +- docs/ZFS_MONITORING.md | 4 +- docs/monitoring/ADAPTIVE_POLLING.md | 9 +- docs/monitoring/PROMETHEUS_METRICS.md | 6 + docs/operations/ADAPTIVE_POLLING_ROLLOUT.md | 12 +- docs/operations/AUDIT_LOG_ROTATION.md | 3 + docs/operations/AUTO_UPDATE.md | 13 +- docs/operations/SENSOR_PROXY_CONFIG.md | 8 +- docs/operations/SENSOR_PROXY_LOGS.md | 8 +- docs/releases/RELEASE_NOTES_v4.md | 137 ++++++ docs/security/SENSOR_PROXY_APPARMOR.md | 16 +- docs/security/SENSOR_PROXY_HARDENING.md | 15 +- docs/security/SENSOR_PROXY_NETWORK.md | 6 +- docs/security/TEMPERATURE_MONITORING.md | 21 +- .../src/components/Settings/NodeModal.tsx | 90 ---- internal/api/router.go | 12 + internal/kubernetesagent/agent.go | 11 +- internal/kubernetesagent/agent_test.go | 33 ++ 48 files changed, 1903 insertions(+), 686 deletions(-) create mode 100644 docs/DEPLOYMENT_MODELS.md create mode 100644 docs/DOCS_AUDIT_V5.md create mode 100644 docs/PULSE_PRO_IMPLEMENTATION.md create mode 100644 docs/SECURITY_AUDIT_2025-12-18.md create mode 100644 docs/UPGRADE_v5.md create mode 100644 docs/releases/RELEASE_NOTES_v4.md diff --git a/README.md b/README.md index 0f3c15240..e83525f16 100644 --- a/README.md +++ b/README.md @@ -32,9 +32,9 @@ Designed for homelabs, sysadmins, and MSPs who need a "single pane of glass" wit ### Pulse AI *(New in 5.0)* - **Chat Assistant**: Ask questions about your infrastructure in natural language -- **Patrol Mode**: Automated health checks with proactive issue detection -- **Auto-Fix**: Automatically resolve common issues with AI-guided remediation -- **Predictive Intelligence**: Forecast problems before they happen +- **Patrol**: Background health checks that generate findings on a schedule +- **Alert Analysis**: Optional AI analysis when alerts fire +- **Cost Tracking**: Track usage and costs per provider/model ### Multi-Platform - **Proxmox VE/PBS/PMG**: Full monitoring and management diff --git a/SECURITY.md b/SECURITY.md index 4cbda6d34..2e804dfe8 100644 --- a/SECURITY.md +++ b/SECURITY.md @@ -41,14 +41,20 @@ environment where `PULSE_DOCKER=true`/`/.dockerenv` is detected. #### Migration Path (Production) -1. **Install the sensor proxy on the Proxmox host that runs Pulse** - ```bash - curl -fsSL https://github.com/rcourtman/Pulse/releases/latest/download/install-sensor-proxy.sh | \ - bash -s -- --ctid --pulse-server https://pulse.example.com:7655 - ``` - - For Docker or standalone hosts where Pulse cannot mount the socket (or when collecting temps from *other* nodes), run the installer with `--standalone --http-mode` so each host exposes its own HTTPS endpoint on port 8443. -2. **Let the installer manage the hardened systemd unit** – it creates the dedicated `pulse-sensor-proxy` user, installs TLS material, and restarts the service safely. -3. **Restart the Pulse container** so it binds to `/run/pulse-sensor-proxy` (for local temps) and registers the HTTPS proxy (for remote temps).

---- - -# Pulse v4.26.1 - -## What's Changed -### New -- Standalone host agents now ship with guided Linux, macOS, and Windows installers that stream registration status back to Pulse, generate scoped commands from **Settings → Agents**, and feed host metrics into alerts alongside Proxmox and Docker. -- Alert thresholds gained host-level overrides, connectivity toggles, and snapshot size guardrails so you can tune offline behaviour per host while keeping a global policy for other resources. -- API tokens now support fine-grained scopes with a redesigned manager that previews command templates, highlights unused credentials, and makes revocation a single click. -- Proxmox replication jobs surface in a dedicated **Settings → Hosts → Replication** view with API plumbing to track task health and bubble failures into the monitoring pipeline. -- Docker Swarm environments now receive service/task-aware reporting with configurable scope, plus a Docker settings view that highlights manager/worker roles, stack health, rollout status, and service alert thresholds. - -### Improvements -- Dashboard loads and drawer links respond faster thanks to cached guest metadata, reduced polling allocations, and inline URL editing that no longer flashes on WebSocket updates. -- Settings navigation is reorganized with dedicated Docker and Hosts sections, richer filters, and platform icons that make agent onboarding and discovery workflows clearer. -- LXC guests now report dynamic interface IPs, configuration metadata, and queue metrics so alerting, discovery, and drawers stay accurate even during rapid container churn. -- Notifications consolidate into a consistent toast system, with clearer feedback during agent setup, token generation, and background job state changes. - -### Bug Fixes -- Enforced explicit node naming and respected custom Proxmox ports so cluster discovery, overrides, and disk monitoring defaults remain intact after edits. -- Hardened setup-token flows and checksum handling in the installers to prevent stale credentials and guarantee the correct binaries are fetched. -- Treated 501 responses from the Proxmox API as non-fatal during failover, restored FreeBSD disk counter parsing, and stopped guest link icons from re-triggering animations on updates. -- Preserved inline editor state across WebSocket refreshes and ensured Docker host identifiers stay collision-safe in mixed environments. -

Admin Bypass Debug Mode 🟡 +**Location:** `internal/api/auth.go:675-691` + +**Finding:** +The `adminBypassEnabled()` function allows bypassing authentication when both `ALLOW_ADMIN_BYPASS=1` and `PULSE_DEV=true` are set. While properly gated for development only: + +```go +if os.Getenv("ALLOW_ADMIN_BYPASS") != "1" { + return +} +if os.Getenv("PULSE_DEV") == "true" || strings.EqualFold(os.Getenv("NODE_ENV"), "development") { + log.Warn().Msg("Admin authentication bypass ENABLED (development mode)") + adminBypassState.enabled = true +} +``` + +**Risk:** Accidental production deployment with these env vars could expose full admin access. + +**Recommendation:** +1. Add prominent warning log at startup if either var is set +2. Consider disallowing in Docker `PULSE_DOCKER=true` mode +3. Document this explicitly as a development-only feature + +--- + +#### M2. Recovery Token Exposure Window 🟡 +**Location:** Session and recovery token stores + +**Finding:** +Recovery tokens for password reset appear to be stored in JSON files. While tokens are hashed: +- File permissions should be verified as 0600 +- Token expiration should be enforced server-side (appears to be implemented) + +**Recommendation:** +1. Verify file permissions are set correctly (0600) during token store initialization +2. Add cleanup routine for expired tokens + +--- + +### LOW SEVERITY + +#### L1. Cookie Security in HTTP Proxies 🔵 +**Location:** `internal/api/auth.go:75-107` + +**Finding:** +When behind an HTTP (non-HTTPS) proxy, cookies fall back to `SameSite=Lax` with `Secure=false`. This is functionally necessary but reduces security. + +**Recommendation:** +1. Log a warning when cookies are set without Secure flag +2. Add documentation recommending HTTPS termination at proxy + +--- + +#### L2. Session Token Entropy 🔵 +**Location:** `internal/api/auth.go:109-118` + +**Finding:** +Session tokens are 32 bytes (256 bits) of entropy via `crypto/rand`, which is excellent. However, the error handling falls back to empty string: + +```go +if _, err := cryptorand.Read(b); err != nil { + log.Error().Err(err).Msg("Failed to generate secure session token") + return "" // Fallback - should never happen +} +``` + +**Recommendation:** +Consider returning an error or panicking rather than returning empty string, as an empty session token could have undefined behavior. + +--- + +#### L3. OIDC State Parameter Validation 🔵 +**Location:** `internal/api/security_oidc.go` + +**Finding:** +OIDC configuration is properly validated and state parameters should be verified during the OAuth flow. This should be confirmed in the callback handler. + +**Recommendation:** +1. Verify state parameter is generated with sufficient entropy +2. Ensure state parameter has short expiration (5-10 minutes) + +--- + +#### L4. Apprise CLI Command Execution 🔵 +**Location:** `internal/notifications/notifications.go` + +**Finding:** +The Apprise CLI path and targets are passed to `exec.CommandContext`. While the CLI path is configurable: + +```go +args := []string{"-t", title, "-b", body} +args = append(args, cfg.Targets...) +execFn := n.appriseExec +``` + +**Risk:** If an attacker can control `cfg.Targets`, they might inject malicious arguments. + +**Recommendation:** +1.
