A flaw was found in Istio. When a RequestAuthentication resource is created with a jwksUri (JSON Web Key Set Uniform Resource Identifier) that points to an internal service, istiod (the Istio control plane daemon) makes an unauthenticated HTTP GET request to that URL. This request does not properly filter out localhost or link-local IP addresses. Consequently, sensitive data can be inadvertently distributed to Envoy proxies via xDS (API for dynamic configuration) configuration, leading to information disclosure. Istio: Istio: Information disclosure through unauthenticated internal service requests The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
