  "details": "In Eclipse Che versions 7.79.0 through 7.121.0, the dashboard backend's POST /dashboard/api/data/resolver endpoint passes a caller-supplied URL directly to an outbound HTTP GET request with no host filtering. An authenticated user can exploit this server-side request forgery (SSRF) to read responses from internal network addresses, including the cloud instance metadata service (169.254.169.254), loopback interfaces, RFC-1918 private ranges, and in-cluster Kubernetes services. The operator-configured allowlist (spec.devEnvironments.allowedSources.urls) is not consulted. The vulnerability is fixed in version 7.122.0, which adds private-address blocking, IPv4-mapped IPv6 bypass prevention, operator allowlist enforcement, and disables HTTP redirects on the outbound request.",
