DescriptionCVE.org

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.

AnalysisAI

Server-side request forgery in Grav CMS before 2.0.4 allows authenticated users holding the api.webhooks.write permission to register webhooks with dangerous cURL protocol handlers (file://, dict://, gopher://) that fire when webhook events trigger. By abusing these unrestricted protocols an attacker can read local files, enumerate process and service information, and pivot to internal-only network services from the trust position of the Grav server. …
