Path traversal issue

In Kibana 7.9.0 to 7.15.1, Kibana is unable to validate .pbf file paths on Microsoft Windows operating systems, which allows malicious users to arbitrarily traverse the Kibana host to load internal .pbf files. CVE-2021-37938

Thank you Dominic Couture for finding this issue.

Upgrade to Kibana 7.15.2.

Information disclosure issue

In Kibana 7.8.0 to 7.15.1, the Kibana JIRA and IBM Resilient connectors could be used to return HTTP response data on internal hosts, which can be hidden from public view. Malicious users with privileges to create connectors can use the JIRA and IBM Resilient connectors to view limited HTTP response data on hosts accessible to the cluster. CVE-2021-37939
