Description
Grav before 2.0.4 fails to restrict cURL protocols in webhook dispatch, allowing authenticated users with api.webhooks.write permission to create webhooks with file://, dict://, or gopher:// URLs. Attackers can trigger webhook events to read local files, access process information, or pivot to internal services via unrestricted protocol handlers.
