Description

Grafana is an open-source platform for monitoring and observability.

Starting with the 8.1 branch, Grafana had a stored XSS vulnerability affecting the core plugin GeoMap.

The stored XSS vulnerability was possible due to map attributions weren't properly sanitized and allowed arbitrary JavaScript to be executed in the context of the currently authorized user of the Grafana instance.

An attacker needs to have the Editor role in order to change a panel to include a map attribution containing 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.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/grafana/grafana, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update github.com/grafana/grafana to 8.5.21 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-0507 is resolved across your whole dependency graph.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.

Red HatImportant

For Grafana package shipped in Red Hat Enterprise Linux, it is not possible to take advantage of this vulnerability without specialized 'editor' access, which reduces the impact of this issue in RHEL. Thus, it is set to Moderate.

Workaround published by Red Hat
Applying the Content-Security-Policy shipped with Grafana would block inline scripts from executing and would mitigate this.
