feat: add CSRF protection, SSRF prevention, and login rate limiting

Security hardening implementing three issues: CSRF Protection (#35): - Session-based CSRF tokens with cryptographically random generation - Constant-time token comparison to prevent timing attacks - CSRF middleware applied to /pages, /sources, /source, and /user routes - Hidden csrf_token field added to all 12+ POST forms in templates - Excluded from /webhook (inbound) and /api (stateless) routes SSRF Prevention (#36): - ValidateTargetURL blocks private/reserved IP ranges at target creation - Blocked ranges: 127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, 169.254.0.0/16, ::1, fc00::/7, fe80::/10, plus multicast, reserved, test-net, and CGN ranges - SSRF-safe HTTP transport with custom DialContext for defense-in-depth at delivery time (prevents DNS rebinding attacks) - Only http/https schemes allowed Login Rate Limiting (#37): - Per-IP rate limiter using golang.org/x/time/rate - 5 attempts per minute per IP on POST /pages/login - GET requests (form rendering) pass through unaffected - Automatic cleanup of stale per-IP limiter entries - X-Forwarded-For and X-Real-IP header support for reverse proxies Closes #35, closes #36, closes #37

 | Session cookie Secure | `false` (works over plain HTTP)  | `true` (requires HTTPS)         |
 The CSRF cookie's `Secure` flag and Origin/Referer validation mode are
 determined per-request based on the actual transport protocol, not the
 environment setting. The middleware checks `r.TLS` (direct TLS) and the
 `X-Forwarded-Proto` header (TLS-terminating reverse proxy) to decide:
 - **Direct TLS or `X-Forwarded-Proto: https`**: Secure cookies, strict
  Origin/Referer validation.
 - **Plaintext HTTP**: Non-Secure cookies, relaxed Origin/Referer
  checks (token validation still enforced).
 This means CSRF protection works correctly in all deployment scenarios:
 behind a TLS-terminating reverse proxy, with direct TLS, or over plain
 HTTP during development. When running behind a reverse proxy, ensure it
 sets the `X-Forwarded-Proto: https` header.
 All other differences (log format, security headers, etc.) are
 independent of the environment setting — log format is determined by
 TTY detection, and security headers are always applied.

 ## Entrypoints
 This repository adheres to the
 [Scripts to Rule Them All](https://github.com/github/scripts-to-rule-them-all)
 standard: normalized scripts in `script/` are the entrypoints for the
 development workflow, and the Makefile targets are thin shims that call
 them. We provide:
 - `script/bootstrap` — install all dependencies (idempotent)
 - `script/setup` — make a fresh clone ready for development
  (bootstrap, then install-precommit)
 - `script/projectname` — output the project name ("webhooker")
 - `script/test` — run the test suite
 - `script/lint` — run golangci-lint
 - `script/fmt` — format all code (writes)
 - `script/fmt-check` — check formatting (read-only)
 - `script/check` — run test, lint, and fmt-check
 - `script/docker` — build the Docker image tagged via `script/projectname`
 - `script/cibuild` — CI entrypoint: `docker build .` (the Dockerfile
  runs the checks, so a green build implies a green repo)
 - `script/precommit` — pre-commit checks (`go mod tidy` guard, then
  `script/check`)
 - `script/install-precommit` — install the git pre-commit hook that
  runs `script/precommit`

 beside the event database. After each write the archive handle is closed
 and reopened, debounced to at most once per second, so an operator can
 move the archive file away for offline archiving without stopping the
 service; a moved or removed archive file is recreated automatically on
 the next write. An optional `expiry` in the target's config JSON (e.g.
 `{"expiry":"720h"}`) is validated when the target is created — the
 default (unset or the literal `never`) keeps rows forever — and rows
 older than the expiry are pruned each time the archive is (re)opened. An

 as raw text. Large payloads are truncated to keep messages reasonable.

 ## TODO
-See [TODO.md](TODO.md).
+### Completed: Code Quality (Phase 1 of MVP)
 - [x] Rename Processor → Webhook, Webhook → Entrypoint in code
      ([#12](https://git.eeqj.de/sneak/webhooker/issues/12))
 - [x] Embed templates via `//go:embed`
      ([#7](https://git.eeqj.de/sneak/webhooker/issues/7))
 - [x] Use `slog.LevelVar` for dynamic log level switching
      ([#8](https://git.eeqj.de/sneak/webhooker/issues/8))
 - [x] Simplify configuration to prefer environment variables
      ([#10](https://git.eeqj.de/sneak/webhooker/issues/10))
 - [x] Remove redundant `godotenv/autoload` import
      ([#11](https://git.eeqj.de/sneak/webhooker/issues/11))
 - [x] Implement authentication middleware for protected routes
      ([#9](https://git.eeqj.de/sneak/webhooker/issues/9))
 - [x] Replace Bootstrap with Tailwind CSS + Alpine.js
      ([#4](https://git.eeqj.de/sneak/webhooker/issues/4))
 ### Completed: Core Webhook Engine (Phase 2 of MVP)
 - [x] Implement webhook reception and event storage at `/webhook/{uuid}`
 - [x] Build event processing and target delivery engine
 - [x] Implement HTTP target type (fire-and-forget with max_retries=0,
      retries with exponential backoff when max_retries>0)
 - [x] Implement database target type (store events in per-webhook DB)
 - [x] Implement log target type (console output)
 - [x] Webhook management pages (list, create, edit, delete)
 - [x] Webhook request log viewer with pagination
 - [x] Entrypoint and target management UI
 ### Completed: Per-Webhook Event Databases
 - [x] Split into main application DB + per-webhook event DBs
 - [x] Per-webhook database lifecycle management (create on webhook
      creation, delete on webhook removal)
 - [x] `WebhookDBManager` component with lazy connection pooling
 - [x] Event-driven delivery engine (channel notifications + timer-based retries)
 - [x] Self-contained delivery tasks: in the ≤16KB happy path, the engine
      delivers without reading from any database — target config, event
      headers, and body are all carried inline in the channel notification.
      The engine only touches the DB to record results (success/failure).
      Large bodies (≥16KB) are fetched from the per-webhook DB on demand.
 - [x] Database target type marks delivery as immediately successful
      (events are already in the per-webhook DB)
 - [x] Parallel fan-out: all targets for an event are delivered via
      the bounded worker pool (no goroutine-per-target)
 - [x] Circuit breaker for HTTP targets with retries: tracks consecutive
      failures per target, opens after 5 failures (30s cooldown),
      half-open probe to test recovery
 ### Remaining: Core Features
 - [ ] Per-webhook rate limiting in the receiver handler
 - [ ] Webhook signature verification (GitHub, Stripe formats)
 - [ ] Security headers (HSTS, CSP, X-Frame-Options)
 - [x] CSRF protection for forms
      ([#35](https://git.eeqj.de/sneak/webhooker/issues/35))
 - [x] SSRF prevention for HTTP delivery targets
      ([#36](https://git.eeqj.de/sneak/webhooker/issues/36))
 - [x] Login rate limiting (per-IP brute-force protection)
      ([#37](https://git.eeqj.de/sneak/webhooker/issues/37))
 - [ ] Session expiration and "remember me"
 - [ ] Password change/reset flow
 - [ ] API key authentication for programmatic access
 - [ ] Manual event redelivery
 - [ ] Analytics dashboard (success rates, response times)
 - [ ] Delivery status and retry management UI
 ### Remaining: Event Maintenance
 - [ ] Automatic event retention cleanup based on `retention_days`
 ### Remaining: REST API
 - [ ] RESTful CRUD for webhooks, entrypoints, targets
 - [ ] Event viewing and filtering endpoints
 - [ ] Event redelivery endpoint
 - [ ] OpenAPI specification
 ### Future
 - [ ] Email delivery target type
 - [ ] SNS, S3, Slack delivery targets
 - [ ] Data transformations (e.g., webhook-to-Slack message formatting)
 - [ ] JSONL file delivery with periodic S3 upload
 - [ ] Webhook event search and filtering
 - [ ] Multi-user with role-based access

 - Repos follow the
  [Scripts to Rule Them All](https://github.com/github/scripts-to-rule-them-all)
  pattern: the implementation of each Makefile target lives in an executable
  script in `script/` (`script/bootstrap`, `script/setup`, `script/test`,
  `script/lint`, `script/fmt`, `script/fmt-check`, `script/check`,
  `script/docker`), and the Makefile targets are thin shims that call them. The
  scripts must be POSIX sh (`#!/bin/sh`, `set -eu`, no bashisms) so they run in
  minimal containers (e.g. alpine images have no bash); locate the repo root
  with `$(cd "$(dirname "$0")/.." && pwd -P)` and `cd` there before acting. From
  the standard's canonical set we use `bootstrap`, `setup` (make the repo ready
  for development after a fresh clone: runs `bootstrap`, then
  `install-precommit`, plus any repo-specific initialization), `test`, and
  `cibuild`. `script/bootstrap` installs all dependencies idempotently and
  assumes nothing is present: base tools come from nix, apt, brew, or apk
  (detected in that order; apt runs noninteractive). For node it uses the
  installed node if present; otherwise it installs a PINNED node version via
  nvm, first installing nvm itself if missing — from a hash-verified GitHub
  release archive (never `curl | sh`), with bash installed as an explicit
  prerequisite since nvm requires bash. yarn is then pinned via
  `corepack prepare yarn@<version> --activate`. Never install "latest" or "lts";
  always exact versions. `script/cibuild` runs the CI build: it changes to the
  repo root and runs `docker build .`; the Gitea workflow calls it. Four further
  scripts are our own extensions to the standard: `script/check` runs
  `script/test`, `script/lint`, and `script/fmt-check`; `script/precommit` is
  what the git pre-commit hook runs, and it calls `script/check`;
  `script/install-precommit` installs the git pre-commit hook (the `make hooks`
  target shims to it); and `script/projectname` (literally that filename) simply
  outputs the project's name. Scripts that need the name call
  `script/projectname` — e.g. `script/docker` assembles its image tag from it —
  so those scripts stay byte-identical across all repos. Repo-type-specific
  pre-commit extras (e.g. `go mod tidy` verification in Go repos) belong in
  `script/precommit`, not in the hook itself. Model scripts are at
  `https://git.eeqj.de/sneak/prompts/raw/branch/main/script/<name>`. The README

  layer stays cached until dependencies change.
 - **Dockerfiles must use a separate lint stage for fail-fast feedback.** Go
  repos use a multistage build where linting runs in an independent stage based
  on the `golangci/golangci-lint` image (pinned by hash). This stage runs
  `make fmt-check` and `make lint` before the full build begins. The build stage
  then declares an explicit dependency on the lint stage via
  `COPY --from=lint /src/go.sum /dev/null`, which forces BuildKit to complete
  linting before proceeding to compilation and tests. This ensures lint failures
  surface in seconds rather than minutes, without blocking on dependency
  download or compilation in the build stage.
    The standard pattern for a Go repo Dockerfile is:
    ```dockerfile
    # Lint stage — fast feedback on formatting and lint issues
    # golangci/golangci-lint:v2.x.x, YYYY-MM-DD
    FROM golangci/golangci-lint@sha256:... AS lint
    WORKDIR /src
    COPY go.mod go.sum ./
    RUN go mod download
    COPY . .
    RUN make fmt-check
    RUN make lint
    # Build stage
    # golang:1.x-alpine, YYYY-MM-DD
    FROM golang@sha256:... AS builder

    # Runtime stage
    FROM alpine@sha256:...
    COPY --from=builder /app /usr/local/bin/app
    ENTRYPOINT ["app"]
    ```
    Key points:
    - The lint stage uses the `golangci/golangci-lint` image directly (it
      includes both Go and the linter), so there is no need to install the
      linter separately.
    - `COPY --from=lint /src/go.sum /dev/null` is a no-op file copy that creates
      a stage dependency. BuildKit runs stages in parallel by default; without
      this line, the build stage would not wait for lint to finish and a lint
      failure might not fail the overall build.
    - If the project uses `//go:embed` directives that reference build artifacts
      (e.g. a web frontend compiled in a separate stage), the lint stage must
      create placeholder files so the embed directives resolve. Example:
      `RUN mkdir -p web/dist && touch web/dist/index.html web/dist/style.css`.
      The lint stage should not depend on the actual build output — it exists to
      fail fast.
    - If the project requires CGO or system libraries for linting (e.g.
      `vips-dev`), install them in the lint stage with `apk add`.
    - The build stage runs `make test` after compilation setup. Tests run in the
      build stage, not the lint stage, because they may require compiled
      artifacts or heavier dependencies.

        - `WriteTimeout` on the `http.Server`.
        - `IdleTimeout` on the `http.Server`.

    - **Authentication and session security:**
        - Rate limiting on password-based authentication endpoints. API keys are
          high-entropy and not susceptible to brute force, so they are exempt.
        - CSRF tokens on all state-mutating HTML forms. API endpoints
          authenticated via `Authorization` header (Bearer token, API key) are
          exempt because the browser does not attach these automatically.
        - Passwords stored using bcrypt, scrypt, or argon2 — never plain-text,
          MD5, or SHA.
        - Session cookies set with `HttpOnly`, `Secure`, and `SameSite=Lax` (or
          `Strict`) attributes.
    - **Reverse proxy awareness:**
        - True client IP detection when behind a reverse proxy
          (`X-Forwarded-For`, `X-Real-IP`). The application must accept
          forwarded headers only from a configured set of trusted proxy
          addresses — never trust `X-Forwarded-For` unconditionally.
    - **CORS:**
        - Authenticated endpoints must restrict `Access-Control-Allow-Origin` to
          an explicit allowlist of known origins. Wildcard (`*`) is acceptable
          only for public, unauthenticated read-only APIs.
    - **Error handling:**
        - Internal errors must never leak stack traces, SQL queries, file paths,
          or other implementation details to the client. Return generic error
          messages in production; detailed errors only when `DEBUG` is enabled.
    - **TLS:**
        - Services never terminate TLS directly. They are always deployed behind
          a TLS-terminating reverse proxy. The service itself listens on plain
          HTTP. However, HSTS headers and `Secure` cookie flags must still be
          set by the application so that the browser enforces HTTPS end-to-end.
    This list is non-exhaustive. Apply defense-in-depth: if a standard security
    hardening measure exists for HTTP services and is not listed here, it is
    still expected. When in doubt, harden.

 pre-1.0. No git tags exist. main (afe88c6) is a working webhook proxy
 with auth, CSRF/SSRF protections, login rate limiting, Slack target,
 policy compliance (#6), and pinned lint tooling (#55). Note: TODO.md was
 deliberately deleted from this repo in f9a9569 (2026-03-01, #6); its
 content was folded into the README TODO section, which this draft
 reconstructs as of 2026-07-06.
 # Next Step
 Implement automatic event retention cleanup based on retention_days: a
 periodic maintenance job that deletes Events, Deliveries, and
 DeliveryResults older than the parent webhook's retention_days from each
 per-webhook event database. The field exists on the Webhook model and
 the README promises the behavior, but nothing enforces it, so event
 databases currently grow without bound.
 # Completed Steps
 - 2026-08-07 Update golangci-lint to v2.12.2 (Docker image digest in
  `Dockerfile`, release-archive sha256 pins in `script/bootstrap`),
  adopt the canonical `.golangci.yml` (v2 `linters.settings` layout so
  `lll`/`funlen`/`cyclop`/`dupl` thresholds actually apply), and fix
  all newly surfaced lint findings
 - 2026-07-07 Adopted scripts-to-rule-them-all: `script/` entrypoints,
  Makefile shims, README Entrypoints section
 - 2026-03-25 pin golangci-lint Docker image for linting (#55)
 - 2026-03-18 CSRF middleware detects TLS per-request, fixing login over
  plain HTTP and behind reverse proxies (#54)
 - 2026-03-17 root path redirects based on auth state (#52)
 - 2026-03-17 CSRF protection, SSRF prevention for HTTP delivery targets
  with DNS rebinding defense, and per-IP login rate limiting (#42)
 - 2026-03-17 Slack target type for incoming webhook notifications (#47)
 - 2026-03-17 Dockerfile absolute paths and static linking (#49);
  absolute dev DATA_DIR default and clarified env docs (#46)
 - 2026-03-05 security headers middleware, session regeneration on
  login, request body size limits (#41)
 - 2026-03-04 tests for delivery, middleware, and session packages
  (#32); removed globals.Buildarch (#31)
 - 2026-03-04 1.0 MVP merge: Webhook/Entrypoint/Target rename, core
  delivery engine with bounded worker pool and circuit breaker,
  parallel fan-out, per-webhook event databases, management UI (#16)
 - 2026-03-01 repo brought to REPO_POLICIES standards; TODO.md folded
  into README (#6)
 # Future Steps
 - Manual event redelivery from the web UI (replay is a core promised
  capability in the README rationale)
 - Delivery status and retry management UI
 - Per-webhook rate limiting in the receiver handler (per-webhook config
  plus handler enforcement; global limits must not apply to receiver
  endpoints)
 - Webhook signature verification for GitHub and Stripe HMAC formats
 - API key authentication for programmatic access (APIKey model exists;
  Bearer token middleware does not)
 - REST API v1
    - CRUD for webhooks, entrypoints, targets
    - event viewing and filtering endpoints
    - event redelivery endpoint
    - OpenAPI specification
 - Analytics dashboard: success rates, response times, volume
 - Session expiration tuning and a remember-me option
 - Password change and reset flow
 - Later, nice to have
    - email delivery target type
    - SNS and S3 delivery targets
    - data transformations (e.g. webhook to Slack message formatting)
    - JSONL file delivery with periodic S3 upload
    - webhook event search and filtering
    - multi-user with role-based access control
