In typical multi-tenant deployments, repository managers can set up automated webhook targets for registry events. Because destination validation lacks IP address resolution checks, an authenticated tenant can target internal cluster services or cloud provider metadata endpoints. However, an attacker cannot supply arbitrary HTTP methods or directly capture full response payloads, containing the overall blast radius.", "threat_severity": "Moderate"}
