CVE-2023-0594: Grafana

Medium severity, CVSS 5.4. EPSS: 9.2% chance of exploitation in the next 30 days.

Grafana is an open-source platform for monitoring and observability. Starting with the 7.0 branch, Grafana had a stored XSS vulnerability in the trace view visualization. The stored XSS vulnerability was possible due the value of a span's attributes/resources were not properly sanitized and this will be rendered when the span's attributes/resources are expanded. An attacker needs to have the Editor role in order to change the value of a trace view visualization to contain JavaScript. This means that vertical privilege escalation is possible, where a user with Editor role can change to a known password for a user having Admin role if the user with Admin role executes malicious JavaScript viewing a dashboard. Users may upgrade to version 8.5.21, 9.2.13 and 9.3.8 to receive a fix.

Affected products

• Grafana Grafana: from 7.0.0, before 8.5.21 (fixed in 8.5.21); from 9.2.0, before 9.2.13 (fixed in 9.2.13); from 9.3.0, before 9.3.8 (fixed in 9.3.8)
