CVE-2020-7015Network attack vector

Stored XSS via unsafe TSVB visualization rendering

Published Jun 3, 2020 · Updated Aug 4, 2024

Stored XSS in Elastic Kibana 5.4.1 through 6.8.9 and 7.0.0 through 7.7.0 allows remote authenticated users to run browser script. TSVB persists attacker-controlled visualization content and renders it without adequate neutralization, causing embedded script to execute when the visualization is edited. The attacker must create or edit TSVB content, and a victim editor must open it; the script then acts with that user's Kibana privileges.
