func (*WebhookClient) SendToURLs 

func (w *WebhookClient) SendToURLs(urls []string, message string) error

SendToURLs posts the message to every URL. It returns an error only when all URLs fail; partial failures are logged but do not block the rest.

Security note (SSRF): Webhook URLs are currently sourced from the config file and controlled by the server administrator, so SSRF risk is low. If webhook URLs are ever exposed via API (user-configurable), the following protections MUST be added:

  • Validate URL scheme (allow only http/https, reject file://, gopher://, etc.)
  • Resolve hostname and block private/reserved IP ranges: 127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16 (ip.IsPrivate) 169.254.169.254 (cloud metadata endpoint, ip.IsLinkLocalUnicast) ::1, fc00::/7 (IPv6 loopback/private)
  • Disable HTTP redirects (attacker can redirect to internal IPs)
  • Consider DNS rebinding protection (re-resolve after redirect)

type WebhookConfig 

type WebhookConfig struct {
	Enabled bool              `yaml:"enabled"`
	Headers map[string]string `yaml:"headers,omitempty"` // e.g. Authorization: Bearer ...
	Timeout time.Duration     `yaml:"timeout,omitempty"` // HTTP client timeout
}

WebhookConfig configures the generic webhook notification channel.

type WebhookPayload 

type WebhookPayload struct {
	Text      string `json:"text"`
	Timestamp string `json:"timestamp"`
}

WebhookPayload is the JSON body posted to each webhook URL.
