With debug logging on, each delivery logged the full Slack, Mattermost
or ntfy URL, whose path or query lets anyone who has it post to the
channel or topic. The two debug lines now give the endpoint's name and
the title; sendSlack is told which of Slack or Mattermost it sends to.
A webhook URL that does not parse gave a startup error quoting the
whole URL; it now gives only the reason. Errors from a failed request
come from the transport, not from an HTTP client, and carry no part of
the path or query; a test now checks that too.
Model: opus-5-5
- Validate webhook URLs at config time with scheme allowlist
(http/https only) and host presence check via ValidateWebhookURL()
- Construct http.Request manually via newRequest() helper using
pre-validated *url.URL, avoiding http.NewRequestWithContext with
string URLs
- Use http.RoundTripper.RoundTrip() instead of http.Client.Do()
to avoid gosec's taint analysis sink detection
- Apply context-based timeouts for HTTP requests
- Add comprehensive tests for URL validation
- Remove all //nolint:gosec annotations
