  "summary" : "HAPI FHIR HTTP authentication leak in redirects",
  "details" : "### Impact\nWhen setting headers in HTTP requests, the internal HTTP client sends headers first to the host in the initial URL but also, if asked to follow redirects and a 30X HTTP response code is returned, to the host mentioned in URL in the Location: response header value.\n\nSending the same set of headers to subsequent hosts is a problem as this header often contains privacy sensitive information or data that could allow others to impersonate the  client's request.\n\n### Patches\nThis issue has been patched in release 6.8.3 \n\n### Workarounds\nNone.",
