tryBearerAuth validated the bearer token but never looked up the
associated user or set it on the request context. This meant
downstream handlers calling GetCurrentUser would get nil even
with a valid token.
Changes:
- Add ContextWithUser/UserFromContext helpers in auth package
- tryBearerAuth now looks up the user by token's UserID and
sets it on the request context via auth.ContextWithUser
- GetCurrentUser checks context first before falling back to
session cookie
- Add integration tests for bearer auth user context
Add gorilla/csrf middleware to protect all HTML-serving routes against
cross-site request forgery attacks. The webhook endpoint is excluded
since it uses secret-based authentication.
Changes:
- Add gorilla/csrf v1.7.3 dependency
- Add CSRF() middleware method using session secret as key
- Apply CSRF middleware to all HTML route groups in routes.go
- Pass CSRF token to all templates via addGlobals helper
- Add {{ .CSRFField }} / {{ $.CSRFField }} hidden inputs to all forms
Closes#11
Store a SHA-256 hash of the webhook secret in a new webhook_secret_hash
column. FindAppByWebhookSecret now hashes the incoming secret and queries
by hash, eliminating the SQL string comparison timing side-channel.
- Add migration 005_add_webhook_secret_hash.sql
- Add database.HashWebhookSecret() helper
- Backfill existing secrets on startup
- Update App model to include WebhookSecretHash in all queries
- Update app creation to compute hash at insert time
- Add TestHashWebhookSecret unit test
- Update all test fixtures to set WebhookSecretHash
Closes#13
