Anso 37b12379c1 fix(stacks): refuse file-explorer delete/rename/chmod on protected stack files (#1202)
* fix(stacks): refuse file-explorer delete/rename/chmod on protected stack files

Previously the per-stack file explorer treated PROTECTED_STACK_FILES
(compose.yaml, compose.yml, docker-compose.yaml/.yml, .env) as a UI
hint only. A direct API call from any user with stack:edit could
delete or rename compose.yaml and break the stack irrecoverably
because the next deploy would fail to find a compose file and the
write was unrecoverable without a DB backup. The frontend
DeleteFileConfirm enforced a type-to-confirm gate but a stale UI or a
scripted client bypassed it.

FileSystemService now refuses the destructive ops at the service layer
with a new PROTECTED_FILE error code that the route layer surfaces as
409. The compose-editor save path (PUT /files/content) and the
upload-overwrite path (POST /files/upload writing a same-named file)
remain unblocked because both are legitimate ways to update
compose.yaml. Tests pin the allowed paths so a future tightening can
not silently regress them.

The protection is scoped to entries at the stack root; subdirectory
files happen to share a protected name (e.g., a snapshot under
backups/compose.yaml) are not blocked because compose CLI only reads
the root file. A trailing-slash bypass is closed by stripping trailing
separators before the basename check.

Frontend DeleteFileConfirm needs no change. Its existing toast.error
surface renders the friendly server message.

* fix(stack-files): drop polynomial regex from protected-file helpers

CodeQL js/polynomial-redos flagged the /\/+$/ pattern used to strip
trailing slashes from relPath in isProtectedRelPath and
protectedFileError. The regex is bounded in practice (the upstream
validator rejects '//' anywhere in the path) but the static analyzer
cannot follow that dataflow guarantee and would have flagged any
future caller that skips the validator.

Replace the two callsites with a small stripTrailingSlash helper that
uses endsWith + slice. Bounded O(1), no regex, no analyzer alert. The
inline comment documents the upstream invariant so a future reader
does not reintroduce the /+ quantifier.

Sencho dashboard

What Sencho is

Sencho is for homelab operators, small DevOps teams, and platform engineers who run services on Docker Compose, want a graphical interface without giving up file-on-disk workflows, and need to manage more than one machine without SSH gymnastics or a VPN.

It runs as a single container on your hardware and gives you a UI for the work you currently do over SSH on compose stacks: deploying, editing files, watching logs, restarting containers, browsing volumes, and recovering from failures. Your compose files stay on the host filesystem and remain the source of truth.

A Sencho instance is autonomous. To manage another machine, you install a second Sencho on it and connect them with a long-lived API token; the primary dashboard then acts as a transparent HTTPS proxy across your fleet. There is no SSH and no exposed Docker socket. For nodes behind NAT or strict firewalls, the Pilot Agent establishes a single outbound WebSocket tunnel to the primary, so the remote host opens no inbound port at all.

Most capabilities are free in the Community tier. A few advanced automation and fleet-control features ship in paid tiers; pricing lives at sencho.io/pricing.


Capabilities

Stacks

  • Full Compose lifecycle: create, deploy, restart, stop, pull
  • Monaco editor with diff preview before save and one-click rollback
  • Git-sourced stacks pulled and synced from any repository
  • File explorer for compose, env, and supporting files
  • Stack labels for grouping and bulk operations
  • App Store with LinuxServer.io templates

Observability

  • Aggregated log search and stream across every container in the fleet
  • Live container stats, health checks, and image-update notifications
  • Threshold alerts for CPU, memory, and network
  • Read-only audit log of every action
  • Network topology view of containers, networks, and nodes

Fleet

  • Multi-node management via authenticated HTTP and WebSocket proxy
  • Fleet view with grid and topology layouts
  • Fleet snapshots of compose and env across the fleet
  • Pilot Agent for nodes behind NAT or strict firewalls
  • Node compatibility checks before deploying

Quick start

Sencho runs in a single container.

services:
  sencho:
    image: saelix/sencho:latest
    container_name: sencho
    restart: unless-stopped
    ports:
      - "1852:1852"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./data:/app/data
      # 1:1 Compose Path Rule: the host path MUST match the container path
      - /opt/docker:/opt/docker
    environment:
      - COMPOSE_DIR=/opt/docker
      - DATA_DIR=/app/data
docker compose up -d

Open http://your-server:1852 and create your admin account.

Always front Sencho with a TLS-terminating reverse proxy in production. See the self-hosting guide for hardening, environment variables, and reverse-proxy examples.

Run with docker run instead
docker run -d --name sencho \
  -p 1852:1852 \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v sencho_data:/app/data \
  -e COMPOSE_DIR=/opt/docker \
  saelix/sencho:latest

For the full walkthrough, see the quickstart guide.


Adding remote nodes

To manage a second machine, install Sencho on it the same way, then add it from the primary dashboard with its URL and a long-lived API token. The primary proxies authenticated HTTPS and WebSocket requests to the remote instance. No SSH, no exposed Docker socket, no agent process on the remote. Nodes behind NAT or strict firewalls can opt into the Pilot Agent for outbound-only connectivity.

See the multi-node guide for the full token-bearer flow.
