Summary
A user with Editor permissions can craft a dashboard whose table (TableNG) panel contains a malicious field name that executes as a script in the browser of any user who views the dashboard (stored cross-site scripting). A flaw in Grafana allows authenticated 'Editor' users to inject malicious scripts into a table panel's field names.
Viewing the compromised dashboard executes the script in the victim's browser, risking data theft or client-side attacks. The requirement for elevated privileges limits the overall exposure.
Red Hat products do not use the vulnerable code and hence are not affected. Red Hat severity: Moderate — CVSS 5.7 (CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:L/A:L).
