Cross-site scripting (XSS) vulnerability in Elasticsearch Kibana 4.x before 4.0.3 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
Kibana versions 4.0 to 4.6, 5.0 to 5.6.12, and 6.0 to 6.4.2 contain an error in the way authorization credentials are used when generating PDF reports. If a report requests external resources plaintext credentials are included in the HTTP request that could be recovered by an external resource provider.
