Prior to 30.3.8, the optional /proxy endpoint contains an incomplete server-side request forgery blocklist. When the endpoint is enabled, the URL validator does not reject the RFC 6598 shared address range 100.64.0.0/10. An unauthenticated remote attacker can cause the draw.io server to request internal services that are reachable in this range, potentially disclosing data from Carrier-Grade NAT, Kubernetes, cloud, or overlay-network addresses. This vulnerability is fixed in 30.3.8."}],"source":{"advisory":"GHSA-xc39-mcq4-fr4q","discovery":"UNKNOWN"}}}}
