When the `HTTPS_PROXY` environment variable is not configured, the console component fails to verify Transport Layer Security (TLS) certificates for outbound connections. A network-positioned attacker (Man-in-the-Middle) can exploit this vulnerability to intercept the cluster pull-secret while it is being sent to console.redhat.com. This pull-secret is a critical credential that provides access to Red Hat container registries and cloud services, potentially leading to unauthorized access and sensitive information disclosure."], "mitigation": {"lang": "en:us", "value": "To mitigate this issue, ensure that the HTTPS_PROXY environment variable is configured for the affected console component. This will enable proper TLS verification for outbound connections to console.redhat.com.
