Description

OpenMetadata through 2.0.2 contains a server-side request forgery vulnerability in the URLValidator.validateURL function that fails to properly resolve DNS hostnames and validate internal addresses. Users permitted to create or update EventSubscription can set webhook destinations to internal hosts, allowing the server to send requests to private networks and cloud metadata endpoints while returning HTTP status codes that enable blind SSRF probing.
