Description Michael Kaplan 2020-06-19 14:00:06 UTC 
Kibana versions before 6.8.9 and 7.7.0 contains a stored XSS flaw in the TSVB visualization. An attacker who is able to edit or create a TSVB visualization could allow the attacker to obtain sensitive information from, or perform destructive actions, on behalf of Kibana users who edit the TSVB visualization.

Comment 1 Joshua Padman 2020-06-25 03:11:38 UTC 
https://github.com/elastic/kibana/commit/a418dc66fa128be74e4de45b04727b35bc37634f is likely the fix especially given the updates to the docs "Less in TSVB does not support custom plugins or inline JavaScript."
Comment 2 Joshua Padman 2020-06-25 03:12:29 UTC 
Mitigation:

To mitigate this vulnerability you can set  "metrics.enabled: false" in kibana.yml
