52ae9a1f1c fix: detect TLS per-request in CSRF middleware to fix login
All checks were successful
check / check (push) Successful in 2m0s
The CSRF middleware previously tied its PlaintextHTTPRequest wrapping
and cookie Secure flag to the IsDev() environment check. This meant
production mode always assumed HTTPS, which broke login in two common
deployment scenarios:

1. Production behind a TLS-terminating reverse proxy: gorilla/csrf
   assumed HTTPS but r.TLS was nil, causing Origin/Referer scheme
   mismatches and 'referer not supplied' errors.

2. Production over direct HTTP (testing/development with prod config):
   the Secure cookie flag prevented the browser from sending the CSRF
   cookie back on POST, causing 'CSRF token invalid' errors.

The fix detects the actual transport protocol per-request using r.TLS
(direct TLS) and the X-Forwarded-Proto header (reverse proxy). Two
gorilla/csrf instances are maintained — one with Secure cookies for TLS
and one without for plaintext — since the csrf.Secure option is set at
creation time. Both instances share the same signing key, so cookies
are interchangeable between them.

Behavior after fix:
- Direct TLS: Secure cookies, strict Origin/Referer checks
- Behind TLS proxy (X-Forwarded-Proto: https): same as direct TLS
- Plaintext HTTP: non-Secure cookies, relaxed Origin/Referer checks
  (csrf.PlaintextHTTPRequest), token validation still enforced

Closes #53

60786c5019 feat: add CSRF protection, SSRF prevention, and login rate limiting (#42)
All checks were successful
check / check (push) Successful in 4s
## Security Hardening

This PR implements three security hardening issues:

### CSRF Protection (closes #35)

- Session-based CSRF tokens with cryptographically random 256-bit 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 webhook POSTs) and `/api` (stateless API)

### SSRF Prevention (closes #36)

- `ValidateTargetURL()` blocks private/reserved IP ranges at target creation time
- 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` in the delivery engine for defense-in-depth (prevents DNS rebinding attacks)
- Only `http` and `https` schemes allowed

### Login Rate Limiting (closes #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 every 5 minutes
- `X-Forwarded-For` and `X-Real-IP` header support for reverse proxies

### Files Changed

**New files:**
- `internal/middleware/csrf.go` + tests — CSRF middleware
- `internal/middleware/ratelimit.go` + tests — Login rate limiter
- `internal/delivery/ssrf.go` + tests — SSRF validation + safe transport

**Modified files:**
- `internal/server/routes.go` — Wire CSRF and rate limit middleware
- `internal/handlers/handlers.go` — Inject CSRF token into template data
- `internal/handlers/source_management.go` — SSRF validation on target creation
- `internal/delivery/engine.go` — SSRF-safe HTTP transport for production
- All form templates — Added hidden `csrf_token` fields
- `README.md` — Updated Security section and TODO checklist

`docker build .` passes (lint + tests + build).

1fbcf96581 security: add headers middleware, session regeneration, and body size limits (#41)
All checks were successful
check / check (push) Successful in 1m47s
## Summary

This PR implements three security hardening measures:

### Security Headers Middleware (closes #34)

Adds a `SecurityHeaders()` middleware applied globally to all routes. Every response now includes:
- `Strict-Transport-Security: max-age=63072000; includeSubDomains; preload`
- `X-Content-Type-Options: nosniff`
- `X-Frame-Options: DENY`
- `Content-Security-Policy: default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline'`
- `Referrer-Policy: strict-origin-when-cross-origin`
- `Permissions-Policy: camera=(), microphone=(), geolocation=()`

### Session Fixation Prevention (closes #38)

Adds a `Regenerate()` method to the session manager that destroys the old session and creates a new one with a fresh ID, copying all session values. Called after successful login to prevent session fixation attacks.

### Request Body Size Limits (closes #39)

Adds a `MaxBodySize()` middleware using `http.MaxBytesReader` to limit POST/PUT/PATCH request bodies to 1 MB. Applied to all form endpoints (`/pages`, `/sources`, `/source/*`).

## Files Changed

- `internal/middleware/middleware.go` — Added `SecurityHeaders()` and `MaxBodySize()` middleware
- `internal/session/session.go` — Added `Regenerate()` method for session fixation prevention
- `internal/handlers/auth.go` — Updated login handler to regenerate session after authentication
- `internal/server/routes.go` — Added SecurityHeaders globally, MaxBodySize to form route groups
- `README.md` — Documented new middleware in stack, updated Security section, moved items to completed TODO

289f479772 test: add tests for delivery, middleware, and session packages (#32)
Some checks failed
check / check (push) Has been cancelled
## Summary

Add comprehensive test coverage for three previously-untested packages, addressing [issue #28](#28).

## Coverage Improvements

| Package | Before | After |
|---------|--------|-------|
| `internal/delivery` | 37.1% | 74.5% |
| `internal/middleware` | 0.0% | 70.2% |
| `internal/session` | 0.0% | 51.5% |

## What's Tested

### delivery (37% → 75%)
- `processNewTask` with inline and large (DB-fetched) bodies
- `processRetryTask` success, skip non-retrying, large body fetch
- Worker lifecycle start/stop, retry channel processing
- `processDelivery` unknown target type handling
- `recoverPendingDeliveries`, `recoverWebhookDeliveries`, `recoverInFlight`
- HTTP delivery with custom headers, timeout, invalid config
- `Notify` batching

### middleware (0% → 70%)
- Logging middleware status code capture and pass-through
- `LoggingResponseWriter` delegation
- CORS dev mode (allow-all) and prod mode (no-op)
- `RequireAuth` redirect for unauthenticated, pass-through for authenticated
- `MetricsAuth` basic auth validation
- `ipFromHostPort` helper

### session (0% → 52%)
- `Get`/`Save` round-trip with real cookie store
- `SetUser`, `GetUserID`, `GetUsername`, `IsAuthenticated`
- `ClearUser` removes all keys
- `Destroy` invalidates session (MaxAge -1)
- Session persistence across requests
- Edge cases: overwrite user, wrong type, constants

## Test Helpers Added
- `database.NewTestDatabase` / `NewTestWebhookDBManager` — cross-package test helpers for delivery integration tests
- `session.NewForTest` — creates session manager without fx lifecycle for middleware tests

## Notes
- No production code modified
- All tests use `httptest`, SQLite in-memory, and real cookie stores — no external network calls
- Full test suite completes in ~3.5s within the 30s timeout
- `docker build .` passes (lint + test + build)

closes #28

45228d9e99 fix: restrict CORS to same-origin (closes #23)
In dev mode, keep the wildcard origin for local testing convenience.
In production, skip CORS headers entirely since the web UI is
server-rendered and cross-origin requests are not expected.

7d13c9da17 feat: add auth middleware for protected routes
Add RequireAuth middleware that checks for a valid session and
redirects unauthenticated users to /pages/login. Applied to all
/sources and /source/{sourceID} routes. The middleware uses the
existing session package for authentication checks.

f9a9569015 feat: bring repo up to REPO_POLICIES standards (#6)
All checks were successful
check / check (push) Successful in 8s
## Summary

This PR brings the webhooker repo into full REPO_POLICIES compliance, addressing both [issue #1](#1) and [issue #2](#2).

## Changes

### New files
- **`cmd/webhooker/main.go`** — The missing application entry point. Uses Uber fx to wire together all internal packages (config, database, logger, server, handlers, middleware, healthcheck, globals, session). Minimal glue code.
- **`REPO_POLICIES.md`** — Fetched from authoritative source (`sneak/prompts`)
- **`.editorconfig`** — Fetched from authoritative source
- **`.dockerignore`** — Sensible Go project exclusions
- **`.gitea/workflows/check.yml`** — CI workflow that runs `docker build .` on push to any branch (Gitea Actions format, actions/checkout pinned by sha256)
- **`configs/config.yaml.example`** — Moved from root `config.yaml`

### Modified files
- **`Makefile`** — Complete rewrite with all REPO_POLICIES required targets: `test`, `lint`, `fmt`, `fmt-check`, `check`, `build`, `hooks`, `docker`, `clean`, plus `dev`, `run`, `deps`
- **`Dockerfile`** — Complete rewrite:
  - Builder: `golang:1.24` (Debian-based, pinned by `sha256:d2d2bc1c84f7...`). Debian needed because `gorm.io/driver/sqlite` pulls `mattn/go-sqlite3` (CGO) which fails on Alpine musl.
  - golangci-lint v1.64.8 installed from GitHub release archive with sha256 verification (v1.x because `.golangci.yml` uses v1 config format)
  - Runs `make check` (fmt-check + lint + test + build) as build step
  - Final stage: `alpine:3.21` (pinned by `sha256:c3f8e73fdb79...`) with non-root user, healthcheck, port 8080
- **`README.md`** — Rewritten with all required REPO_POLICIES sections: description line with name/purpose/category/license/author, Getting Started, Rationale, Design, TODO (integrated from TODO.md), License, Author
- **`.gitignore`** — Fixed `webhooker` pattern to `/webhooker` (was blocking `cmd/webhooker/`), added `config.yaml` to prevent committing runtime config with secrets
- **`static/static.go`** — Removed `vendor` from embed directive (directory was empty/missing)
- **`internal/database/database_test.go`** — Fixed to use in-memory config via `afero.MemMapFs` instead of depending on `config.yaml` on disk. Test is now properly isolated.
- **`go.mod`/`go.sum`** — `go mod tidy`

### Removed files
- **`TODO.md`** — Content integrated into README.md TODO section
- **`config.yaml`** — Moved to `configs/config.yaml.example`

## Verification
- `docker build .` passes (lint , test , build )
- All existing tests pass with no modifications to assertions or test logic
- `.golangci.yml` untouched
